Question

Factorise the following x^4+x

Answer 1

x(x + 1)(x² - x + 1)

Explanation:

Given

`x^(4)` + x ← factor out x from each term

= x(x³ + 1) ← x³ + 1 is a sum of cubes and factors as

= x(x + 1)(x² - x + 1) ← in factored form

Answer 2

x(x^3 + 1)

Explanation:

x^4 + x

We got the common factor x so, we got:

x(x^3 + 1)

This is the simpliest form it can get

Hope it helped :3
