x3 – x =? A. x(x2 – x) B. x(x – x2) C. x(1 + x) (1 – x) D.

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

x3 – x =? A. x(x2 – x) B. x(x – x2) C. x(1 + x) (1 – x) D. x(x + 1) (1 – x)

Answer»

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

= x(x – 1)(x + 1) \(\because\) a² – b² = (a – b)(a + b)
