Question

Multiply Conjugates Using the Product of Conjugates Pattern

In the following exercises, multiply each pair of conjugates using the Product of Conjugates Pattern
330. (11 − b)(11 + b)

Answer 1

The product is the difference of squares is
`$$\left(11-b\right)\left(11+b\right)=121-{{b}^2}$$`

Explanation:

Explanation

• The given expression is (11-b)(11+b).

• We have to multiply the given expression.

• Square the first term 11. Square the last term b.

`$$\begin{aligned}&(11-b)(11+b)=(11)^(2)-(b)^(2) \\&(11-b)(11+b)=121-b^(2)\end{aligned}$$`
