    you need a common denominator, (x+1)(x+2) in this case...

    2(x+2)+3(x+1)

    ------------------

    (x+2)(x+1)

    distribute those terms in the numerator

    2x+4+3x+3

    -------------

    (x+2)(x+1)

    combine like terms

    5x+7

    ------------

    (x+2)(x+1)

    foil the denominator

    5x+7

    ------------

    x^2+3x+2
