If you get stuck on any of the exercises in these WebWork sets over the next week (these HW sets are due Tues Nov 30), you can post a comment below saying which exercise you’re stuck on and a brief description of what you tried to do, and I will reply with a hint or solution.

For example, you could post the following:

I am stuck on ComplexFractions-Method1: Problem 4. I simplified the complex fraction by multiplying the given numerator by the reciprocal of the given denominator and got to ‘7(a+9)/(81-a^2)’ but I got the error message ‘Your answer can be reduced further.’ I’m not sure how to reduce further!
