    Integration partial fractions

    1. Homework Statement integrate (4x^2 + 3x + 6)/x^2 (x+2) dx 2. Homework Equations don't have sorry.. 3. The Attempt at a Solution firstly = A/x + B/x^2 + C /x+2 , = A(x^2)(x+2) + B(x)(x+2) + C(x)(x^2) equating with the 4x^2 + 3x + 6,then i integrate it,but my ans turn out to...
