Factories: x 3

We have, x 3 – 64x = x(x 2 – 64) By using the formula a 2 – b 2 = (a + b)(a – b) We get, x 3 – 64x = x(x 2 – 64) = x{(x) 2 – (8) 2 } = x(x + 8)(x – 8)

Factories:
x³ – 64x

We have,

x³ – 64x

= x(x² – 64)

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

We get,

x³ – 64x = x(x² – 64)

= x{(x)² – (8)²}

= x(x + 8)(x – 8)
