I am having a problem multiplying these fractions:
This is the process I know for solving these:
1. Factor the numerators and denominators of both fractions.
2. Cross out the common factors. Now I can see what the answer is.
But that isn't working here. I can't find any common factors, so I can't get rid of them:
The answer is but knowing the answer is useless to me because I don't know how to get there.
What am I doing wrong? Is there a different way to multiply fractions? Am I factoring wrong? Why does an x end up in the denominator?
