Exercise 25 Page 698

Recall the distribution of a square of a binomial.

4x^2+36x+81

Practice makes perfect

We can find the product of this expression using polynomial identities. In this case, we have the square of a binomial.

(2x+9)^2

ExpandPosPerfectSquare

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

(2x)^2+2(2x)(9)+9^2

Multiply

(2x)^2+36x+9^2

(a * b)^m=a^m* b^m

2^2x^2+36x+9^2

Calculate power

4x^2+36x+81
