Find the value of y: y² + y − 2.	Answers
A) -1 and 2 B) -2 and -1 C) -2 and 1 D) 1 and 2 E) 0 and 2
That quadratic is factored as follows:
y² + y − 2 = (y − 1)(y + 2).
Now, it is easy to see that the first factor will be 0 when y = 1
Now, it is easy to see that the second factor will be 0 when y = -2
The solutions are:
x	=	-2 and 1 -2 and 1
