Determine if the answer to the expression below will be rational or irrational

-V12 + 3V3

The answer to the expression -√12 + 3√3 can be determined as follows:

√12 = √(4 * 3) = 2√3

Therefore, the expression becomes:

-√12 + 3√3 = -2√3 + 3√3 = √3

Since √3 is an irrational number, the answer to the given expression is irrational.
