# In problems 23-58, perform the indicated operations and simplify. 9 ( 2 x + 1 ) ( 2 x − 1 )

To determine

To calculate: The simplified expression of 9(2x+1)(2x1)

by performing the indicated operations.

Explanation

Given information:

The given algebraic expression is 9(2x+1)(2xâˆ’1).

Formula used:

Use the formula of difference of two squares (x+a)(xâˆ’a)=x2âˆ’a2

and the product rule of exponent for some integer m and n:

(xm)(xn)=xm+n.

Calculation:

By the difference of two squares formula, the simplified expression of 9(2x+1)(2xâˆ’1)

will be:

9(2</
