Exercise 8 Page 86

Notice that the given expression is the product of a conjugate pair of binomials.

4b^2-25

To simplify the given expression, we will expand the product of a conjugate pair of binomials.

(2b-5)(2b+5)

ExpandDiffSquares

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

(2b)^2-5^2

(a * b)^m=a^m* b^m

2^2b^2-5^2

Calculate power

4b^2-25

Since there are no like terms, our expression cannot be simplified any further.
