x3 – 144x =? A. x(x – 12)2 B. x(x + 12)2 C. x(x – 12) (x + 12

1.	x3 – 144x =? A. x(x – 12)2 B. x(x + 12)2 C. x(x – 12) (x + 12) D. none of these
Answer» X³ – 144x = x(x² – 144) (taking x as common from whole) = x(x – 12)(x + 12) a² – b² = (a – b)(a + b)

x3 – 144x =? A. x(x – 12)2 B. x(x + 12)2 C. x(x – 12) (x + 12) D. none of these

Answer»

X³ – 144x = x(x² – 144) (taking x as common from whole)

= x(x – 12)(x + 12) a² – b² = (a – b)(a + b)
