Step-by-step explanation:
We need to find two numbers that add up to
−
12
and those same two numbers have a product of
35
. After some thinking and trial and error, we come up with
−
5
+
−
7
=
−
12
&
−
5
⋅
−
7
=
35
Therefore
−
5
and
−
7
will be our two factors. We have:
(
x
−
5
)
(
x
−
7
)
=
0
as our factored form, and to find the zeros, take the opposite sign to get:
x
=
5
and
