What is the factorization of the quadratic expression 2x² + 8x + 8?
- 2(x + 2)(x +2)
- 2(x + 1)(x +4)
- 2(x + 1)(x +2)
- None of these
Explanation
The expression is 2x² + 8x + 8. First, factor out 2:
→ 2(x² + 4x + 4)
Now factor the quadratic:
→ x² + 4x + 4 = (x + 2)(x + 2)
So the full factorization is 2(x + 2)(x + 2).
