Answer 1

`-2x√(y).`

Explanation:

1. Write the expression.

`√(x^2y) -3√(4x^2y)+√(9x^2y)`

2. Bring the x values out of the square root by taking the square root of them.

`x√(y) -3(2x)√(y)+3x√(y)`

3. Multiply.

`x√(y) -6x√(y)+3x√(y)`

4. Factorize and simplify.

`(x-6x+3x)(√(y))\\ \\(-2x)(√(y))\\ \\-2x√(y)`
