-applauds this kid-

bon travail

hey! i know the answer!!!

Really? I forget how to find solutions involving complex numbers… XD

The quadratic formula ends up with (6±sqrt(-24))/6. Yeech!

That’s an algebra problem, probably Algebra 2, so nobody would take this before high school. I don’t think a 15 year old qualifies for a “kid’s drawing”.

…and I’ve just realize that I’ve forgotten everything I ever learned in that class.

I did this sort of math in middle school! Still a teenager, though.

And no, I don’t remember how to do it.

I did this in like fifth or sixth grade

so damn nice. (‘:

Well Tetris IS more fun than math.

I just played Tetris, and hit my all time best score!

And Puyo is better than Tetris.

The closest thing I’ve played is Dr. Robotnik’s Mean bean Machine, but I hear that they are similar?

Also, Apparantly Ristar bustar is too… I heaven’t even played it. (I HAVE, however, played Ristar.)

I never understood Tetris…

whoever did that is oficially AWESOME

Tetris = geometry = math, right?

This kid needs more crayons: he made the reverse-S piece and line piece the same color.

But the drawing is inaccurate! There should never be two pieces going down at the same time 😛

he’s playing tetris wrong though, the next piece doesn’t pop up until the most recent piece is firm on the ground.

He must be playing on a hacked version on Insane difficulty.

a) Convert to a-h-k-form:

y = 3x²+6x+5

y/3 = x²+2x+5/3

y/3 = x²+2x+1-1+5/3

y/3 = (x+1)²-1+5/3

y/3 = (x+2)²+2/3

y = 3(x+2)²+2

=> Vertex is at (-2/-7), the coefficient of x² ist positive, so the vertex is the low point of the parabola.

b) The vertex is either the low or the high point of the parabula.

c) 3*0²+2*0+5 = 5

The y-intercept is at y = 5.

There are no x-intercepts, because of what we found out in a). We can see that if trying to solve:

0 = 3x²+6x+5

0 = x²+2x+5/3

x1 = -1 + sqrt(1-5/3) & x2 = -1 + sqrt (1-5/3)

Negative numbers have no solution for their squareroot in the x/y-plane.

A+ For this kid he almost won
