Thanks for taking the time to respond and point out my error. I know it doesn't count but had actually read that section before but had forgotten it. Without the factorization of x^3 + 27 I was struggling to find the next step. Evidently the information in that section at has not been reinforced eno...

Hi, I just got sorted this out. The problem is that I omitted a step when factoring the components: x^3 + 27 = (unable to reduce) x^2 + 6x + 9 = (x + 3)(x + 3) x^2 - 9 = (x + 3)(x - 3) x^2 - 3x + 9 = (unable to reduce) The first one is incorrect that it doesn't reduce, it does, it reduces to x^3 + 2...

I have been working through Dr. Rapalje's Algebra texts regarding multiplying and dividing fractions: http://www2.seminolestate.edu/rrapalje/IntermediateAlgebra/Int%20One%20Step%20Ch%202/2204_Mult_Div_Frac.htm I'm having difficulty reducing problem 38 to the solution. The expression starts as: \frac...
