Simplifying the Expression: (-4x + 3) - (7x - 3x² - 1)
This expression involves subtracting one polynomial from another. To simplify it, we need to distribute the negative sign and then combine like terms. Let's break it down step-by-step:
-
Distributing the negative sign:
The minus sign in front of the second parenthesis means we multiply each term inside the second parenthesis by -1:
(-4x + 3) + (-1 * 7x) + (-1 * -3x²) + (-1 * -1)
-
Simplifying the signs:
-4x + 3 - 7x + 3x² + 1
-
Combining like terms:
Identify terms with the same variables and exponents, and combine their coefficients:
3x² + (-4x - 7x) + (3 + 1)
-
Final simplified expression:
3x² - 11x + 4
Therefore, the simplified form of the expression (-4x + 3) - (7x - 3x² - 1) is 3x² - 11x + 4.
