Exercise 64 Page 522

Recall the pattern for the square of a binomial.

a^2+18a+81

Practice makes perfect

We want to simplify the given expression. Recall that the square of a binomial with addition is the sum of the square of the first term, twice the product of the terms, and the square of the last term. ( a+ b)^2= a^2+ 2 a b+ b^2 Let's use the above formula to simplify our expression!

( a+ 9)^2

(a+b)^2=a^2+2ab+b^2

a^2+ 2( a)( 9)+ 9^2

Multiply

a^2+18a+9^2
