Question

y-(y^2)/4 = u

so y = ?

Answer 1

Did u write it complate ???

Answer 2

y^2/4 - y + u = 0
solve quadratic equation for y

Answer 3

Hi @Coolsector

is it y = \[2 \pm 2\sqrt{1-u}\]

Answer 4

Use from delta and 2th equation form :)
Do u know that ?:)

Answer 5

Hi E.ali I graduated from high school 13 years ago, basically I forgot all this kind of stuff

Answer 6

correct

Answer 7

Hi and no problem!
Look if we have this equation and want to find X :
ax^2+bx+C=0
Have this :
We have two answer there X1and X2
(1,2are just name of answers .)
And to find them :
-b+_Delta(under Radical)/2a
Delta=b^2-4ac
Remember that ?
