Exercise 13 Page 374

Start by removing the parentheses.

r^2 + 8r - 5

Practice makes perfect

To simplify the given expression, we will start by removing the first set of parentheses. Then, we will apply the Distributive Property to remove the second set of parentheses. Finally, we will combine like terms.

(4r^2 + 3r - 1) - (3r^2 - 5r + 4)

Remove parentheses

4r^2 + 3r - 1 - (3r^2 - 5r + 4)

Distribute - 1

4r^2 + 3r - 1 - 3r^2 + 5r - 4

Add and subtract terms

r^2 + 8r - 5

There are no other like terms; our expression cannot be simplified any further.
