Hello there!

( (2^2*3^2x^2) -  25) \\ \\  Factoring:  \boxed{36x2-25} \\ \\ (PROOF): \\ \\  (A+B) * (A-B) = \\
         A2 - AB + BA - B2 = \\
         A2 - AB + AB - B2 =  \\
         A2 - B2 \\ \\

Your final answer would be (<span> (6x + 5) • (6x - 5)).

Your correct answer would be (option d).
