Answer:
The answer is
x
=
0
;
x
=
−
12
.
Problem: Complete the square for
x
2
+
12
x
.
Rewrite the equation as a trinomial.
x
2
+
12
x
+
0
Move 0 to the right-hand side.
x
2
+
12
x
=
0
Divide the coefficient of the
x
-term by 2, then square the result. Add the result to both sides.
12
2
=
6
;
6
2
=
36
x
2
+
12
x
+
36
=
36
Factor the perfect square trinomial
x
2
+
12
x
+
36
on the left-hand side.
(
x
+
6
)
2
=
36
Take the square root of both sides and solve for
x
.
√
(
x
+
6
)
2
=
±
√
36
=
x
+
6
=
±
6
x
=
−
6
+
6
=
0
x
=
−
6
−
6
=
−
12
Check
If
x
=
0
:
(
0
)
2
+
12
(
0
)
=
0
0
=
0
If
x
=
−
12
:
(
−
12
)
2
+
12
(
−
12
)
=
0
144
−
144
=
