Apply the Distributive Property.

25r^2-49

Practice makes perfect

We want to simplify the expression by finding the product of the binomials. To do so, we will apply the Distributive Property.

(5r+7)(5r-7)

Distribute (5r-7)

5r(5r-7)+7(5r-7)

Distribute 5r

25r^2-35r+7(5r-7)

Distribute 7

25r^2-35r+35r-49

Add terms

25r^2-49
