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)(a-b)
thus the numerator can be factored into:
then cancel the common factor and you get 6x - 7y
hope this helps.
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!!!!!
you're welcome, Jordyn! :)
