can someone please help. Dividing polynomials... (16x^2-25y^2)divided by (4x+5y)...Please explain your answer...

OpenStudy (anonymous):

All those numbers are squared. So 16x^2 is plus/minus 4x. 25y^2 is plus/minus 5y. The answer would be: (4x+5y)(4x-5y)

OpenStudy (anonymous):

I was told that the answer was just 4x

OpenStudy (aroub):

16x^2 -25y^2 ------------ 4x+5y ok.. first u factor the numerator: (4x-5y)(4x+5y) -------------- 4x+5y now u cancel 5x+5y with 4x+5y : = (4x-5y)

OpenStudy (anonymous):

Is not just 4x.

ok didnt think so
