2x2 + 8 - 4x + 3x - 6x2 + 7
1. 2x2 + 6x - 7x + 8 - 3x2 +1
2. -2x2 - x - 9
3. -x2 - x + 9
4. x2 + 9
1. (2x2 - 3x2) + (-4x + 3x) + (8 + 7) - 6x2 = -7x2 - x + 15
2. Rearranging terms: -2x2 - 6x + 8 + 1 = -2x2 - 6x + 9
3. Rearranging terms: -6x2 - x + 7 + 9 = -6x2 - x + 16, simplifying: -6x2 - x + 16
4. Rearranging terms: 2x2 - 6x2 + 9 = -4x2 + 9
To simplify the expression 2x^2 + 8 - 4x + 3x - 6x^2 + 7, follow these steps:
Step 1: Combine like terms within each set of parentheses.
2x^2 + 8 - 4x + 3x - 6x^2 + 7 can be rewritten as:
(2x^2 - 6x^2) + (-4x + 3x) + 8 + 7
-4x^2 - x + 15
So, the simplified expression is -4x^2 - x + 15.
