Exercise 2 Page 30

Recall the pattern for the square of a binomial.

121-22a+a^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.

(11-a)^2

ExpandNegPerfectSquare

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

11^2-2(11)a+a^2

Multiply

11^2-22a+a^2

Calculate power

121-22a+a^2
