Factories: x3 – 64x – InterviewSolution

1.	Factories: x3 – 64x
Answer» 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)

Factories: x3 – 64x

Answer»

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)
