We know for our problem that the zeroes of our quadratic equation are 
and 
, which means that the solutions for our equation are 
and 
. We are going to use those solutions to express our quadratic equation in the form 
; to do that we will use the <span>zero factor property in reverse:
</span>
<span>
</span>
<span>
Now, we can multiply the left sides of our equations:
</span>
<span>= </span>
=
=
Now that we have our quadratic in the form, we can infer that 
and 
; therefore, we can conclude that 
.

Now that we have our quadratic in the form
Answer:
(-1, -3) and (1, 1)
Step-by-step explanation:
Use a graphing calculator to graph out both lines:
(See picture)
Both lines intersect at points (-1, -3) and (1, 1). These are the solutions for the system of equations.
