Question: 1 / 400

What is the result when simplifying the expression (2x² + 3x) - (4x² - x)?

-2x² + 4x

To simplify the expression (2x² + 3x) - (4x² - x), first, distribute the negative sign across the second set of parentheses. This means that you need to subtract each term inside the parentheses (4x² - x).

Thus, the expression becomes:

2x² + 3x - 4x² + x

Now, combine like terms. Start with the x² terms:

2x² - 4x² = -2x²

Next, combine the x terms:

3x + x = 4x

Now, putting it all together, the simplified expression is:

-2x² + 4x

This confirms that the correct answer is indeed -2x² + 4x. Understanding how to simplify expressions by combining like terms and what it means to distribute negatives is crucial for solving algebraic expressions successfully.
