# Factorize 5x^{3} - 135

5, x - 3, x^{2} + 3x + 9, All of the above

**Solution:**

Given 5x^{3} - 135

Let us factor the polynomial

= 5(x^{3} - 27)

= 5(x^{3} - 3^{3} )

This is the form a³-b³ = (a - b) (a² + ab + b² )

a= x and b= 3

5(x-3)(x^{2} + 3x + 9)

Here, 5, x-3, (x^{2} + 3x + 9) are three factors of the given function

## Factorize 5x^{3} - 135

5, x - 3, x^{2} + 3x + 9, All of the above

**Summary: **

By factorising 5x^{3} - 135 we get 5, x-3, x^{2} + 3x + 9 as its factors.
