Consider the equation y^2-y=6. What is the error with the solution below:
y^2-y=6
y(y-1)=6
y=6 or y-1=6
y=6 or y=7
(6,7)
A. The solution is correct
B. In y^2-y=6, y^2 should've been factored instead of y
C. In y^2-y=6, 6 should've been subtracted on both sides first
D. Instead of y = 6, it should have been y = –6.

well this step is clearly wrong: 
y=6 or y-1=6

wait hold on is y=6 or y-1=6 the error? I'm asking because I got confused
