Question

A rectangle has a height of t? + 7t +6 and a width of 2t + 1.

Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.

Answer 1

2t^3+15t^2+19t+6

Explanation:

(t^2+7t+6)(2t+1)

=t^2*2t+t^2*1+7t*2t+7t*1+6*2t+6*1

=2t^3+15t^2+7t+12t+6

=2t^3+15t^2+19t+6
