What is the factored form of 2x^2+2x-4

A (x + 2) (2x - 1)

B 2 (x + 2) (x - 1)

C 2 (x + 2) (x + 1)

D (2x - 4) (x - 1)

2x^2+2x-4=2 (2x^2+2x-4) / 2=[2 (2x^2) + 2 (2x) - 2 (4) ]/2=[2^2x^2+2 (2x) - 8]/2

2x^2+2x-4=[ (2x) ^2+2 (2x) - 8]/2 = (2x+4) (2x-2) / 2=2 (2x/2+4/2) 2 (2x/2-2/2) / 2

2x^2+2x-4=2 (x+2) (x-1)

Answer: Option B. 2 (x+2) (x-1)
