Final answer:
To solve the given expression, we first combine like terms and simplify.
Step-by-step explanation:
To solve the given expression, we first combine like terms. We add the terms and collect them as follows:
To solve the equation (5x² - 3x + 2) + (-x + 2x² - 4), we need to combine like terms. First, collect the x² terms: 5x² and 2x² which gives us 7x². Then combine the x terms: -3x and -x to get -4x. Finally, combine the constant terms: 2 and -4 which gives us -2. So, the simplified expression is 7x² - 4x - 2.
(5x² - 3x + 2) + (-x + 2x² - 4)
Combining like terms, we have:
5x² + 2x² - 3x - x + 2 - 4
Adding the x² terms, we get:
7x² - 4x - 2
This is the simplified form of the given expression.
