Asked by Roy
What is the sum of all values of x that satisfy the equation (x2 -5x+5)^(x2 +4x-60) =1? Hint: There are three cases to consider
I think I figured out 2 of the cases. The first one being x2 +4x-60=0 while x2 -5x+5=whatever. The second is x2 -5x+5=1 and x2 +4x-60=whatever. But I cant think of a third case
