Consider the quadratic equation y^2 - y = 6. What is the error with the solution below?
y²-y=6
y(y-1)=6
y=6 or y-1=6
y=6 or y-1=6
y=6 or y=7
(6,7)
A. The solution is correct
B. In y²-y=6, y² should have been factored out instead of y.
C. In y²-y=6, y², 6 should have been subtracted on both sides first.
D. Instead of y=6, it should have been y=-6
