Who /quadraticformula/ here? Factorization is for brainlets only.

>opposite of b
>the square of b squared

>>8762408
if you can't show how to derive the quadratic formula, you are a brainlet of the lowest caliber

>>8762421
It seems I've made a typo. I was too consumed by the magnificence of the quadratic formula, I suppose.

Prove to me you aren't a brainlet, anon. I don't believe you.

Mnemonics are for brainlets only. I memorised the formula by just looking at it and using it.

Dumb dumb

>>8762460
I solve all equations through transforms.

>>8762408
heh, you're like a little kid. watch this

Let [math] a, b, c \in R [/math] be positive, then let [math] a, b [/math] be the legs of a right triangle and [math] c [/math] its hypotenuse and let [math] n \leq 2 [/math] where [math] n \in ℕ [/math]

Then

[math] a^{n} + b^{n} = c^{n} [/math]

>>8762468
Prove it brainlet.

wew, lad

disgusting

I bet you need a formula sheet for your work too don't you faggot. Learn to derive formulas by pure inspection

>he doesn't just guess and get it right with his 230 iq
why do you guys even bother? you'll never be able to understand post-anabelian froeboid geometrics. brainlets (sub 160iq) should be euthanized.

[math](p-q)^2=(p+q)^2-4pq[/math]

[math]
\begin{align*}
ax^2 + bx +c &= 0 \\
ax^2 + bx &= -c \; \; \; \; | \; \cdot 4a \\
4a^2x^2 + 4abx &= -4ac \; \; \; \; | \; +b^2 \\
4a^2x^2 + 4abx +b^2 &= b^2 -4ac \\
(2ax + b)^2 &= b^2 -4ac \\
2ax + b &= \pm \sqrt{b^2 - 4ac} \\
2ax &= -b \pm \sqrt{b^2 - 4ac} \\
\displaystyle
x &= \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\end{align*}
[/math]

fucking disgusting
