Exercise 23 Page 510

The product of the sum and difference of the same two terms is the difference of their squares.

49h^2-4

Practice makes perfect

Recall that the product of the sum and difference of the same two terms is the difference of their squares. ( a + b)( a - b)= a^2-b^2 Let's use this formula to simplify the given product.
