Factories: 3x5 – 48x3 – InterviewSolution

1.	Factories: 3x5 – 48x3
Answer» We have, 3x⁵ – 48x³ = 3x³(x² – 16) By using the formula a² – b² = (a + b)(a – b) We get, 3x⁵ – 48x³ = 3x³(x² – 16) = 3x³{(x)² – (4)²} = 3x³(x + 4)(x – 4)

Factories: 3x5 – 48x3

Answer»

We have,

3x⁵ – 48x³

= 3x³(x² – 16)

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

We get,

3x⁵ – 48x³ = 3x³(x² – 16)

= 3x³{(x)² – (4)²}

= 3x³(x + 4)(x – 4)
