Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Expand the expression: \$(6x + 1/(6x))^2 \$
2	Hint	By using algebraic	\$ (a+b)^2 = a^2+b^2+2ab\$
3	Step	After using algebric	\$ (6x)^2 + (1/(6x))^2 + 2 (\cancel(6x))^1(1/\cancel(6x)^1) \$
4	Step	After cancellation ,we get	\$ 36x^2 + 1/(36x^2) + 2 \$

Answer

Problem

Expand the expression:
\$(6x + 1/(6x))^2 \$

Hint

By using algebraic

\$ (a+b)^2 = a^2+b^2+2ab\$

Step

After using algebric

\$ (6x)^2 + (1/(6x))^2 + 2 (\cancel(6x))^1(1/\cancel(6x)^1) \$

Step

After cancellation ,we get

\$ 36x^2 + 1/(36x^2) + 2 \$
