Question

Express the area of the entire rectangle.

Your answer should be a polynomial in standard form.
(3x^2 + 8x + 7) (7x^2)

Answer 1

`21x^(4)+ 56x^(3)+49x^(2)`

Explanation:

When we multiply the two sides together, we get:

(3x²·7x²) + (8x·7x²) + (7·7x²) =

`21x^(4)+ 56x^(3)+49x^(2)`

This is the polynomial in standard form.
