Question

Simplify 4(3r^3+5r-6)-6(2r^3-r^2+4r), and express your answer in the form Ar^2 + Br + C, where A, B, and C are integers.

Accepted Answer

Using the distributive property and combining like terms, we have 4(3r^3+5r-6)-6(2r^3-r^2+4r) = 12r^3+20r-24-12r^3+6r^2-24r. Simplifying, we get 6r^2-4r-24.
