1) (x,y) = no solution
2) x=-2y
-2y-y = 9
-3y = 9
y = -3
x = -2(-3)
x = 6
(x,y) = (6,-3)
X^2 + 4x -12 = (x+6)(x-2)
so
(x+6)(x-2)
---------------- = x - 2
x + 6
f(x) = x -2
answer is B.
because
if x = -6
then y = -6 - 2 = -8
(-6,-8) is the order pair
Hey!
First, let's write the problem,

Factor out the common term, which is 4,

Then, let's factor this part:

We are going to factor it using the difference of squares rule.

Our final factored answer would be,

Thanks!
