Exercise 66 Page 522

Recall the product of a conjugate pair of binomials.

h^2-100

Practice makes perfect

We want to simplify the given expression. Recall that a product of a conjugate pair of binomials can be written as a difference of squares. ( a- b)( a+ b)= a^2- b^2 Let's use the above formula to simplify our expression!

( h- 10)( h+ 10)

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

h^2-10^2
