Exercise 88 Page 63

Use the polynomial identities to expand the square of a binomial.

36x^2-12x+1

Practice makes perfect

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

(6x-1)^2

ExpandNegPerfectSquare

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

(6x)^2-2 * 6x * 1+1^2

Calculate power

36x^2-2 * 6x * 1+1

Multiply

36x^2-12x+1
