Need help
Consider the quadratic 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 have been factored out instead of y
C.
in y^2-y=6, 6 should have been subtracted on both sides first.
D.

Instead of y = 6, it should have been y = –6.

Answer 1

try c

Answer 2

the third line is incorrect
C is the correct option

Answer 3

\[y^2-y-6=0\]

Answer 4

Thanks
