Best Answer

Since it is a division problem, multiply by the reciprocal:

Factored: [ (2x - 3)(2x + 3) ] / (2x + 5) · [ (2x + 5)(2x - 5) ] / [ (2x - 3)(2x - 3) ]

Numerator: (2x - 3)(2x + 3)(2x + 5)(2x - 5)

Denominator: (2x + 5)(2x - 3)(2x - 3)

Cancel: [ (2x + 3)(2x - 5) ] / (2x - 3)

Nothing will cancel; is there a division sign between them?
