The first step for solving this expression is to multiply the parenthesis.

√(45) x^(2) + 2√(90) x + √(75)x + 2√(150)
Simplify the first radical.

3√(5) x^(2) + 2√(90) x + √(75)x + 2√(150)
Simplify the second radical.

3√(5) x^(2) + 2X3√(10) x + √(75)x + 2√(150)
Simplify the third radical.

3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 2√(150)
Simplify the final radical.

3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 10√(6)
Lastly,, calculate the product of 2 × 3
√(10)x to get your final answer.

3√(5) x^(2) + 6√(10) x + 5√(3)x + 10√(6)
Let me know if you have any further questions.
