Question

Factorise:
1. 5x³– 15x

Answer 1

Step-by-step explanation:

= 5x³– 15x

= -10x³

Is the answer

Answer 2

Given,

$5x^{3}-15x$

Here, we have to find the factors of this given expression.

By using factorization splitting method to find the factors

Here we have to take common $5x$, we get

$5x^{3}-15x=0$

$5x(x^{2}-3)=0$

$5x=0$, $(x^{2} -3)=0$

$x^{2} -3=0$

$x^{2} =3$

$x=\sqrt{3}$

$x=0,\sqrt{3}$

Therefore, the factors of $5x^{3}-15x$ is $0$ and $\sqrt{3}$.
