y=4x2+4x−8

Separate the values with a comma.

cwrw238 · Answer

one zeros of the equation is 1 which means that one factor is (x - 1)

cwrw238 · Answer

so we have y =  (x - a)(4x + a) = 4x^2 + 4x -8)
can you find the values of a ?

cwrw238 · Answer

* sorry its 
(x - 1)(4x + a) = 4x^2 + 4x  - 8
