    That looks like an online quiz. If this problem is for a grade, it is forum policy not knowingly to help with such problems.

    1. Combine the fractions.
    2. Cross multiply.

    This should be easier now. can you complete it?

    Alternatively you can multiply through each term by 2(x+1)(x+2) to clear the fraction

    Should be: 1/(x+1) - 1/(x+2) = 1/2 ; brackets very important here
