Question

Here we go again, last one for the night. Thanks for the help!

9x^2 - 25y^2 / 3x+5y

Answer 1

what's to be done? simplify?

on the numerator is a difference of squares

= (3x - 5y)(3x + 5y)/(3x + 5y)

= 3x - 5y, as long as y is not -3x/5

Answer 2

you can factor out the top part of the equation
into (3x - 5y) and (3x +5y)
so the new equation looks like this (3x-5y)(3x+5y) / (3x+5y)
the bottom (3x+5y) cancels the top (3x+5y) so all you have left over is (3x-5y)

Answer 3

just says find quotient. show all work. (jamesm)
