Question

How do you simplify `2x(5x+10)`?

Answer 1

`=10x^2 + 20x`

Explanation:

To simplify this expression, we want to distribute the `2x` term to each term inside the parentheses:

`color(blue)(2x)(5x+10)`

`=color(blue)(2x) xx 5x+color(blue)(2x) xx 10`

`=(2xx5)x^2 + (2xx10)x`

`=10x^2 + 20x`
