Question

Factorise fully 7x^3-35

Answer 1

Answer: 7(x^3-5)

Explanation:

the common number between 7 and 35 is seven( 7*1=7, 7*5=35)

so with the 7 outside the parenthesis we end up having inside the parenthesis x^3 and 5 because x=1 and 7*1=7 and the 5 because 7*5=35 so if we distribute the seven we would get the original answer

Answer 2

`7(x^3-5)`

Explanation:

Given expression:

`7x^3-35`

To factor the given expression, begin by rewriting 35 as 7 · 5:

`\implies 7x^3-7 \cdot 5`

Now factor out the common term 7:

`\implies 7(x^3-5)`
