Answer: The numerator will be 2x^2 - x - 6.
For the first fraction, we need to multiply it by 2x. So we will have:
2x(x + 1) = 2x^2 + 2x
For the second fraction, we need to multiply it by 3. So we will have:
3(x + 2) = 3x + 6
Now, we just have to subtract the numerators.
2x^2 + 2x - 3x - 6
2x^2 - x - 6
