1.	(2x – 32x3) = ?(i) 2(x-4)(x+4)(ii) 2x(1-2x)2(iii) 2x(1+2x)2(iv) 2x(1-4x)(1+4x)
Answer» (iv) 2x (1 – 4x) (1 + 4x) let us consider (2x – 32x³) = 2x (1 – 16x²) by taking 2x as the common factor By using the formula a² – b² = (a – b) (a + b) = 2x (1 – 4x) (1 + 4x)

(2x – 32x3) = ?(i) 2(x-4)(x+4)(ii) 2x(1-2x)2(iii) 2x(1+2x)2(iv) 2x(1-4x)(1+4x)

Answer»

(iv) 2x (1 – 4x) (1 + 4x)

let us consider (2x – 32x³) = 2x (1 – 16x²) by taking 2x as the common factor

By using the formula a² – b² = (a – b) (a + b)

= 2x (1 – 4x) (1 + 4x)
