When mn+m^2-30n^2 is divided by m-5n, what is the quotient. Thank you
what is (m-5n)(m+6n)/(m-5n) ?
Don't be put off by the extra variable. You can easily factor
m^2+m-30, right? That's what you have if n=1.
I don't understand. Then what is the final answer
(m-5n)(m+6n)/(m-5n) = m+6n
There is an interesting video showing how to do long division with two variables at
Scroll most of the way down the page to where the heading is "More than One Variable".
Follow its method using your problem and it should become clear.
