Question

How do you multiply `(x – 3)(x^2 + 7x – 8)`?

Answer 1

`x^3+4x^2-29x+24`

Explanation:

Given:`" "color(blue)((x-3))color(brown)((x^2+7x-8))`

This is the same as:

#color(brown)(color(blue)(x)color(brown)((x^2+7x-8))color(blue)(-3) color(brown)((x^2+7x-8)))#

`x^3+7x^2-8x-3x^2-21x+24`

`x^3+4x^2-29x+24`
