(x + 1)(x + 2)(x - 2)
(x + 1) 2(x + 2) (x - 2)
(x + 1)2 (x + 2)2
(x + 1)2 (x + 2)(x - 2)
Correct answer is D
\((x^{2} + x)^{2} - (2x + 2)^{2}\)
= \((x^{2} + x + 2x + 2)(x^{2} + x - (2x + 2))\)
= \((x^{2} + 3x + 2)(x^{2} - x - 2)\)
= \(((x + 1)(x + 2))((x + 1)(x - 2))\)
= \((x + 1)^{2} (x + 2)(x - 2)\)
