Exercise 21 Page 510

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

g^2-100

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.

(g+10)(g-10)

ExpandDiffSquares

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

g^2-10^2

Calculate power
