Answer:
x = 6
Step-by-step explanation:
First, separate the problem into
Then, Subtract 9 from both sides of the equation.
Simplify.
Multiply 3 to each side, which will give you -2x = 4x - 36
Subtract 4x from each side -2x - 4x = 4x - 36x - 4x
Combine like terms: -6x = -36
Divide both sides by -6
Your answer should be 6

As the steps show above, the idea is to factor the radicand into smaller pieces where one of those pieces is the largest perfect square possible. In this case, 36 is the largest factor of 180 that's a perfect square. Then I used the rule to break up the root.
The parenthesis used at the very end is to help separate the from the
term. The "i" is not under the square root.
