Answer 2

To solve the equation 14 - (2 + 3x - x^2) = x^2 + 4x - 9, you can follow these steps:

1. Distribute the negative sign inside the parentheses:

   14 - 2 - 3x + x^2 = x^2 + 4x - 9

2. Combine like terms on both sides of the equation:

   (14 - 2) - 3x + x^2 = x^2 + 4x - 9

   12 - 3x + x^2 = x^2 + 4x - 9

3. Move all terms involving x to one side of the equation:

   x^2 - 3x - x^2 - 4x = -9 - 12

   -7x = -21

4. Now, divide both sides by -7 to isolate x:

   -7x / -7 = -21 / -7

   x = 3

So, the solution to the equation is x = 3.
