# Which of the following shows the complete factorization x^{3} + 3x^{2}?

Factorization of expressions is important if we want to simplify a complicated expression. Often, factorized form is easier to read or analyze as compared to the expanded form.

## Answer: The factorized form of x^{3} + 3x^{2 }is x^{2}(x + 3).

Let's understand the solution.

**Explanation:**

Given expression: x^{3} + 3x^{2}

To factorize the equation, we take x^{2} common.

Therefore, x^{3} + 3x^{2} = x^{2}(x + 3).
