Question

How do you simplify `x(x^2 + 6x - 7)`?

Answer 1

`x^3+6x^2-7x`

Explanation:

Each term in the bracket is `color(blue)"multiplied"` by x. This is called the `color(blue)"distributive law".`

`rArrcolor(red)(x)(x^2+6x-7)`

`=(color(red)(x)xx x^2)+(color(red)(x)xx6x)-(color(red)(x)xx7)`

`=x^3+6x^2-7x`
