The first step to solving this is to factor out the first perfect square
now factor out the second perfect square
then factor out the second perfect square
the root of a product is equal to the product of the roots of each factor
reduce the index of the radical and exponent with 2 of the first square root
12
reduce the index of the radical and exponent with 2 of the second square root
12x³
reduce the index of the radical and exponent with 2 of the third square root
12x³y²
this means that the correct answer to your question is 12x³y² .
