When you have two numbers multiplied together, and the result is zero, then one or both of the numbers must be zero.
So (2x - 3 ) = 0, or (4x + 4) =0, or both.
Can you solve 2x - 3 = 0 ?
Can you solve 4x + 4 = 0 ?

Therefore 2x-3=0 and 4x+4=0
2x=3 so x = 3/2 or 1.5
4x=-4 so x= -4/4 or -1
x= -1 or 1.5

(2x - 3)(4x + 4) = 0
since f(x) is in factored form, to solve for x let each term be equated with zero
2x-3=0
x=3/2
4x+4=0
4x=-4
x=-1

8x²+8x-12x-12=0 (/4)
2X²-x-3=0
delta = 1 + 24 = 25
x' = (1+5)/4= 3/2
x" = (1-5)/4= -1

What you do is make one part of the left equation equal to zero.
x=-1
x=3/2
