36x^2  49y^2 divided by 6x + 7y
meaning 36x^2  49y^2 is on top and
6x + 7y is on bottom.
Please help, my teacher nor course book covers when there are different variables

(36x^2  49y^2)/(6x + 7y)
notice that the numerator is a difference of two squares,, recall:
a^2  b^2 = (a+b)(ab)
thus the numerator can be factored into:
(6x+7y)(6x7y)/(6x+7y)
then cancel the common factor and you get 6x  7y
hope this helps.

Jai,
Oh my gosh, thank you so much. I even understand exactly how you go the answer. I've been doing the tutoring at my school for almost 2 days with the same tutor and they cannot explain it on an easy to understand level. I really really appreciate your help!!!!!
