The quick solution: -5a+8 The long solution: We first distribute the "-5" to the terms inside the parentheses and get "-5a+10". With the parentheses gone, we can combine "+10" and "-2" to get "+8". We finally get the solution "-5a+8".

Lisa please ignore the errata on your previous post. And the GCF of these is not 52w, instead it is w^2. You see, GCF is the common factor, and I think you've been trying to find the LCM and multiplying 13 and 13.
