Simplifying the Expression: (−x2−3x+3)−(−x2−9x+6)
This problem involves subtracting two polynomials. To simplify this expression, we need to follow these steps:
-
Distribute the negative sign: The negative sign in front of the second set of parentheses means we multiply each term inside the parentheses by -1.
This gives us: (−x2−3x+3) + (x2 + 9x - 6)
-
Combine like terms: Identify terms with the same variables and exponents and combine their coefficients.
- x2 terms: -x2 + x2 = 0
- x terms: -3x + 9x = 6x
- Constant terms: 3 - 6 = -3
-
Write the simplified expression: After combining like terms, the simplified expression is: 6x - 3
Therefore, the simplified form of (−x2−3x+3)−(−x2−9x+6) is 6x - 3.
