Question

What is the leading coefficient and constant of this equation?

(8r^3 + 2r^2 + 1) - (7 - 7r^3 +3r^2)

Answer 1

The leading coefficient is 15

The constant is -6

Explanation:

So first open up all the parentheses:

`8r^3+2r^2+1-7+7r^3-3r^2 = 15r^3-r^2-6`

The leading coefficient is 15

The constant is -6
