If someone could help me in a step by step format so that I could get it I'd REALLY REALLY APPRECIATE IT. I thought I had the GCF for the first one as 7x^7 but when I went to check it didn't work out with 35x^7 unless I did something wrong. With the second one, I got confused when the textbook was showing the switching of the variables. #1 Factor completely and if it's a prime, state that it's a prime: 7x^9 - 28x^8 - 35x^7 #2 Same directions 10s^2 + 4st - 6t^2Answer by stanbon(57342)   (Show Source): You can put this solution on YOUR website!#1 Factor completely and if it's a prime, state that it's a prime: 7x^9 - 28x^8 - 35x^7 Common Factor: 7x^7 Ans: 7x^7(x^2 - 4x -5) Factor again: Ans: 7x^7(x-5)(x+1) =========================== #2 Same directions 10s^2 + 4st - 6t^2 Common Factor: 2 Ans: 2(5s^2 + 2st - 3t^2) Factor again: Ans: 2(5s^2 + 5st - 3st - 3t^2) 2(5s(s+5)-3t(s+t)) 2(s+5)(5s-3t) ======================= Cheers, Stan H.
