Question

What is the product? (5r+2)(3r-4)

Answer 1

First distribute 5r to the 3r and -4 to get 15r^2-20r

Second distribute 2 towards 3r and -4 to get 6r-8

Aftr your whole eqausion should look like

15r^2-20r+6r-8

Since 15r^2 cant be added to anything leave it as is and the rest of the equation should be this

15r^2-14r-8

It should be easy to figure out from there

Answer 2

15r^2 − 14r − 8
