Question 863929: I am having problems figuring out 2 questions. The first one is factor the trinomial or state that it is prime:
x^2+6x-7, I have been working on this and believe that it is prime?
and the second one is: 2x-2/x * 5x^2/4x-4, I have been working on this and think it might be 5x/2?
Thank you

x^2+6x-7

(x+7)(x-1)

(2(x-1))/x)*(5x^2/(4(x-1))
=5x/2
