Step-by-step explanation:
Given
3
(
x
2
+
2
)
=
18
Solve for
x
1) Divide both sides by
3
After you divide, you will get this:
x
2
+
2
=
6
2) Subtract
2
from both sides to isolate the
x
2
term
x
2
=
4
3) Find the square roots of both sides
x
=
±
2
. . . . . . . . Check . . . . . . .
Using the original equation, sub in either
+
2
or
−
2
in the place of
x
. The equation should still equal
18
3
(
x
2
+
2
)
=
18
1) Sub in
−
2
3
(
(
−

)
2
+
2
)
should still equal
18
2)Square the
−
2
3
(
4
+
2
)
should still equal
18
3) Add inside the parentheses

should still equal
