Correct answer: B. (x + 2)(3 − 2x)

Explanation

6 − x − 2x² = −(2x² + x − 6) = −(2x − 3)(x + 2) = (3 − 2x)(x + 2). Check: (x + 2)(3 − 2x) = 3x − 2x² + 6 − 4x = 6 − x − 2x². Answer: (x + 2)(3 − 2x).6 − x − 2x² = −(2x² + x − 6) = −(2x − 3)(x + 2) = (3 − 2x)(x + 2)। जाँच: (x + 2)(3 − 2x) = 3x − 2x² + 6 − 4x = 6 − x − 2x²। उत्तर: (x + 2)(3 − 2x)।
