Question

How do you multiply `-6x ( 2x ^ { 2} + 6x + 7)`?

Answer 1

See a solution process below:

Explanation:

To solve this problem you multiply each term within the parenthesis by the term outside the parenthesis:

`color(red)(-6x)(2x^2 + 6x + 7) =>`

`(color(red)(-6x) xx 2x^2) + (color(red)(-6x) xx 6x) + (color(red)(-6x) xx 7) =>`

`-12x^3 + (-36x^2) + (-42x)`

`-12x^3 - 36x^2 - 42x`
