To simplify the expression (9 - 1x + 2x) - (2x^2 - 3x + 5), you can follow these steps:
1. Combine like terms:
(9 + 2x) - (2x^2 - 3x + 5)
2. Simplify:
2x + 9 - (2x^2 - 3x + 5)
3. Combine like terms:
2x + 9 - 2x^2 + 3x - 5
4.Simplify:
-2x^2 + 5x + 4
Therefore, the simplified form of the expression is -2x^2 + 5x + 4.
