Premed biologist here, i have to do a stupid math course because "muh education."
x^2 - 10x + 25 = 0
How in the world in the name of sweet baby jesus can i solve this and others like it?
For those of you who have taken university level math (no highschool kids please) how can i do it?
I get it's probably easy for those of you spoogelords who have a mental illness and actually find enjoyment in playing with numbers, but please go easy on me, i actually care about relevant visible physical things like life on earth.
Just use the quadratic equation and end this thread.

(x-5)(x-5)=0 x=5 And this is ninth grade level math at the least
Nathan Green
Also if you're premed you'll have to take physics because it's on the MCAT. So don't be a premed if you can't do this level of math.
Bentley Robinson
Is there some way to do this for all equations?
Like how did you know to use 5's?
Camden Evans
Please be trolling. If you're not go look up quadratic equation.
Jacob Rogers
If you can't understand middle school level algebra you should change majors
How did you get into college?

you foil it, but backwards essentially

>you dont remember that one random thing taught 5 years ago that was never used again >how did you get into collage?
lol fine alright ive reviewed quadratic equations
now before you hypocrite chits say another word, please solve this long division question within the next 10 seconds:
oh wait, it was something you learned 5 years ago that you never used again. ____ 33/627
eat it

You'll never make it in medicine, you're too much of a confirmed brainlet. I'd rather go to a black female doctor than your moronic self. Get fucked, faggOP.
Dominic Murphy
It's most likely a falseflag or a typical troll. Won't stop people from taking the bait though.

>you dont know how to play with numbers as well as i do, you'll never be a good biologist
LOL?
Zachary Brooks
You should really learn to appreciate mathematics it is actually quite invaluable when it comes to abstract thinking. Plus it is also good for your discipline. I do not think I would have the work ethic I have without taking calculus II.

Holy shit, this guy is a brainlet AND a pedophile cartoon posting degenerate! Coincidence? Think not.

do not respond to this and let this troll thread die

Adam Morris
hahaha gtfo you numberphile
my cartoons are vastly superior to your shit discipline
have fun calculating numbers and scribbling on paper solving problems greater minds have already solved whilst i make 170k starting (GP) and save lives DAILY.
pathetic attempt to put down superior minds.

REMINDER
Brandon Ortiz
See this, faggOP.
Evan Moore
OP here that's not me.
All i wanted was to know how to solve the problem.
I'm sorry for being mad and taking out my frustrations on math people.

>implying long division is hard More like fifteen years ago because I'm not underage, I use it once a year, and I STILL remember it. Find the largest multiple of the denominator that fits into the remainder, subtract that multiple * denominator from remainder to get new remainder, repeat until remainder is smaller than denominator. I also remember how to do polynomial long division which I haven't used at all. I'm a fucking code monkey, we're supposed to be bad at math, what's your excuse premed who will be responsible for human lives?
Cooper Powell
Isn't this just simple factoring?I thought premed students were supposed to be smart.

There are multiple methods you could solve this. Technically, four methods. One involves using your calculator to find the roots of the equation. (real roots can be thought of as "x-intercepts").
You can either (in decreasing difficulty): - Factor - Complete the square - Quadratic formula.
Be caution when using the quadratic formula. It's very simple to use, and because of that, also the easiest to make a simple mistake on [if you're plugging n chugging on a calculator which is what you'll most likely do].
If I had to solve this, I'd use complete the square because it's a decent medium between quadratic formula and factoring. It sounds like a lot of work to do but it's really not (and it shouldn't be, 9th graders do this stuff in the first few weeks of school).
1.) ""Move"" c to the other side. This should result in [math]x^2 - 10x = -25[/math] 1.) Divide b in half and square it. Whatever number this gives you, you add to both sides. In this case, we have: [math]\left( - \frac{10}{2} \right)^{2} = -5^2 = 25[/math]. Since we got [math]25[/math], we add [math]25[/math] to both sides of the equation, which should give you: [math]x^2 - 10x + 25 = 0[/math] (Recall that [math]-25[/math] is the additive inverse of [math]25[/math], which is why you now have zero on the right side). 3.) "Factor" this perfect square. No need to do anything complicated here. Notice the number we had before squaring? That's what you're gonna factor the quadratic into. This should result in: [math](x-5)^2 = 0[/math] 4.) Take the square root of both sides to get rid of the exponent. This should result in: [math](x-5) = 0[/math] 5.) Solve like normal: [eqn] \begin{aligned} (x - 5) &= 0 \\ x - 5 &= 0 \\ x &= 5 \end{aligned} [/eqn] Now let's "test" our so-called "solution". [eqn] \begin{aligned} x^2 - 10x + 25 &= 0 \\ (5)^2 - 10(5) + 25 &= 0 \\ 25 - 50 + 25 &= 0 \\ -25 + 25 &= 0 \\ 0 &= 0 \end{aligned} [/eqn] [math]0 = 0[/math] is a true statement. Therefore, that's your solution.

>33/627 Using first year high school maths: First find 627/33 because that is easier to do 627/3 = 209 209/11 = 19 33/627 = 1/(627/33) = 1/19 Which is about 0.05 something All done in 10 seconds
Gabriel Richardson
He was attempting to write long division notation as is seen by the underscores on the previous line. 627/33 is what he wrote given that. But yes, it's fucking easy and he's just repeating the opinions reinforced in his bubble of math-illiterates.

>ninth grade AHAHAHAHAHA
such is the caliber of people who seriously respond to homework threads
