Hi, how do I fully solve this problem?
I've factorised both denominators, but not the numerators.
Please help.
Thanks
You have the following:
. . . . .
You say that you have factored both of the denominators. I do not see any way of factoring the first denominator, since it is not a difference of squares or cubes, and contains no common factors, so I would be interested in seeing your work for this. I will guess that the other factorization led to the following:
. . . . .
To learn how to factor the first numerator, try here. You should get the following:
. . . . .
Since the last term in the second numerator is not , I don't see any factoring you can do here, either. So you're stuck with just the one cancellation, and then multiplying the rest out.
