hey guys is it cool to be in basic math 8)

[CaptainBubba]

if 10(x^2+2xy+y^2)/2=5 and x+y=z then find z.

(x^2+2xy+y^2) = (x+y)^2

10((x+y)^2)/2 = 5(x+y)^2 = 5

(x+y)^2 = 1

let u = (x+y)

u^2 = 1

u = 1

z = 1

faggots

NEW QUESTION FOR ZELDA:

Prove that every even integer greater than 2 can be written as the sum of two primes.

This ones easy guys come on.

actually you're only half right

z= 1 or -1

I'm Babylonian dude, we ignore negative answers to quadratics doncha know.
