(2x – 32x3) =? A. 2(x – 4) (x + 4) B. 2x(1 – 2x)2 C. 2x(1 + 2

1.	(2x – 32x3) =? A. 2(x – 4) (x + 4) B. 2x(1 – 2x)2 C. 2x(1 + 2x)2 D. 2(1 – 4x) (1 + 4x)
Answer» (2x – 32x³) = 2x(1 – 16x²) (taking 2x as common from whole) = 2x(1 – 4x)(1 + 4x) a² – b² = (a – b)(a + b)

(2x – 32x3) =? A. 2(x – 4) (x + 4) B. 2x(1 – 2x)2 C. 2x(1 + 2x)2 D. 2(1 – 4x) (1 + 4x)

Answer»

(2x – 32x³) = 2x(1 – 16x²) (taking 2x as common from whole)

= 2x(1 – 4x)(1 + 4x) a² – b² = (a – b)(a + b)
