 Question 341826: This problem involves factoring terms that include positive and negative exponents. For some reason I just can't see it: (3x+2)(2/3)(6x-5)^(-1/3)(6)+(6x-5)^(2/3)(3) I keep coming up with: I factored out (6x-5)^(-1/3)(2/3)(3)[(3x+2)+2(6x-5)^(3/3) <- (or 1) So that simplifies to: (6x-5)^(-1/3)(2)(3x+2)+12x-10 Further simplified to: (6x-5)^(-1/3)[6x+4+12x-10] The (6x-5)^(-1/3) moves to the denominator and 18x-6 remains in the numerator. I don't know where I am going wrong with this. I know the denominator is right, but the answer shown for the numerator is 30x-7 and I just can't figure out how to get to that.
