Exercise 20 Page 31

Recall the pattern for the square of a binomial.

64h^2-64hn+16n^2

Practice makes perfect

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

(8h-4n)^2

ExpandNegPerfectSquare

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

(8h)^2-2(8h)(4n)+(4n)^2

Multiply

(8h)^2-64hn+(4n)^2

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

8^2h^2-64hn+4^2n^2

Calculate power

64h^2-64hn+16n^2
