Question

How do you simplify `-3x^2(x^2 + 3x)`?

Answer 1

See the solution process below:

Explanation:

To simplify this expression multiply each term within the parenthesis by the term outside the parenthesis:

`color(red)(-3x^2)(x^2 + 3x) =>`

`(color(red)(-3x^2) * x^2) + (color(red)(-3x^2) * 3x) =>`

`-3x^4 - 9x^3`
