Problem Statement

You have provided the expression 5 + (2-3xy)(2+3xy) and asked for a solution. Let's solve it step by step.

Solution

To solve the expression 5 + (2-3xy)(2+3xy), we can use the distributive property of multiplication over addition.

First, let's multiply the two binomials: (2-3xy)(2+3xy).

Using the FOIL method (First, Outer, Inner, Last), we get:

2 * 2 + 2 * 3xy - 3xy * 2 - 3xy * 3xy

Simplifying further, we have:

4 + 6xy - 6xy - 9x^2y^2

The terms 6xy and -6xy cancel each other out, leaving us with:

4 - 9x^2y^2

Now, we can substitute this simplified expression back into the original expression:

5 + (4 - 9x^2y^2)

Combining like terms, we have:

9 - 9x^2y^2

Therefore, the solution to the expression 5 + (2-3xy)(2+3xy) is 9 - 9x^2y^2.

Please note that this solution assumes that x and y are variables and not specific values. If you have specific values for x and y, please provide them so we can evaluate the expression further.
