Question

6y=4ysquared-4
y =?

Answer 1

4y^2 - 6y - 4 = 0
simplify by dividing by 2
2y^2 - 3y - 2 = 0
now we need to factor this (if possible):
we need two numbers which add up to -3 and multiply to give 2(-2)
these are -2 and +1
s0:
(2y + 1 )(y - 2 ) = 0
so y = 1, -0.5

Answer 2

double check math it may be 2, -.5

Answer 3

Jimmy rep was right, need to simplify first!

Answer 4

No I am correct and you can verify if you want by checking wolframalpha.
(2y + 1 )(y - 2 ) = 0
so y =-.5, (2(-.5)+1)= 0
and
y= 2 (2-2)=0
