Best ResponseYou've already chosen the best response.0a) 2(9x2  16y2) b) 2(3x + 4y)(3x  4y) c) (9x  16y)(2x + 2y) d) Can't be factored.

Best ResponseYou've already chosen the best response.0It's b. 9x^2  16y^2 is the difference of two squares. (3x+4y)(3x4y)

Best ResponseYou've already chosen the best response.0but because the question asks you to factor completely you want b.

Best ResponseYou've already chosen the best response.0the original expression is 18x2  32y2

Best ResponseYou've already chosen the best response.0so the first step is to factor out the 2: 2(9x^2  16y^2) and then factor the second part as I mentioned above.

Best ResponseYou've already chosen the best response.0ah I see what you did gotcha. Yes B is more accurate.

Best ResponseYou've already chosen the best response.0I didn't simplify the first factorization I gave correctly.

Best ResponseYou've already chosen the best response.04 (8 y^29) and 2(3x + 4y)(3x  4y) are the same
