Integration by partial fractions
Distinct linear factors
(3x-4)/(x-1)(x-2) = 1/(x-1) + 2/(x-2)
disguised linear factors
(x² +15)/(x² -1)(x² +2)
Repeated linear factors
(5x² - 19x - 17)/(x-1)(x-2)²
Non repeated quadratic factors
If the denominator contains a factor ax² + bx + c then the fraction corresponding to it is
(px+ q)/(ax² + bx + c)
