SOLUTION:

Step 1:

In this question, we are given the following:

[tex](\text{ 3x+ 5\rparen\lparen3x-5\rparen}[/tex]

Step 2:

The details of the solution are as follows:

[tex]\begin{gathered} Multiplying\text{ this, we have that:} \\ (\text{ 3x+ 5\rparen\lparen3x-5\rparen= 9x}^2-15x+15x-25\text{ = 9x}^2\text{ - 25} \end{gathered}[/tex]

CONCLUSION:

The final answer is:

[tex]9x^2\text{ - 25}[/tex]
