partial
fraction decomposition of (5x^3 + 8x^2 + 36x + 36) / (x^4 + 9x^2) ---------------------------------------------- ----------------------------------------------- observe that degree of denominator > degree of numerator (so that long division is not needed) factorise the x² in the denominator then split into A/x + B/( x²) + [(Cx+D) / ( x² +9)] answer and some steps are given below ================ * * ================ ![]() integration formulae more problems on integration |
