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
.
