Solution:
- Simplify the right side of the equation: \( -x^2 - 3x - 2 + 2x^2 = x^2 - 3x - 2 \)
- Set up the equation: \( x^2 + x + 6 = x^2 - 3x - 2 \)
- Subtract \( x^2 \) from both sides: \( x + 6 = -3x - 2 \)
- Add \( 3x \) to both sides: \( 4x + 6 = -2 \)
- Subtract 6 from both sides: \( 4x = -8 \)
- Divide by 4: \( x = -2 \)
Final Answer: x = -2
