  1. Case 1: Denominator is a product of linear factors with no repeats

    Find the partial fractions of:

    1. x+7(x+3)(x−1)\frac{x + 7}{(x + 3)(x - 1)}
    2. 4x+3x2+x\frac{4x + 3}{x^{2} + x}
  2. Case 2: Denominator is a product of linear factors with repeats

    Find the partial fractions of :

    1. 3x2−5(x−2)3\frac{3x^{2} - 5}{(x - 2)^{3}}
    2. 2x−1x2+10x+25\frac{2x - 1}{x^{2} + 10x + 25}
  3. Case 3: Denominator contains irreducible quadratic factors with no repeats

    Find the partial fractions of :

    2x2+5x+8x3−8x\frac{2x^{2} + 5x + 8}{x^{3} - 8x}

  4. Case 4: Denominator contains irreducible quadratic factors with repeats

    Find the partial fractions of:

    3x4+x3+1x(x2+1)2\frac{3x^{4} + x^{3} + 1}{x(x^{2} + 1)^{2}}

  5. First perform long division, then partial fraction decomposition

    Find the partial fractions of:

    1. x3−3x2+4xx2−3x2\frac{x^{3} - 3x^{2} + 4x}{x^{2} - 3x 2}
    2. 2x2+14x+24x2+6x−16\frac{2x^{2} + 14x + 24}{x^{2} + 6x - 16}
