expand (x^3-4x^2+2x+5)/(x(x+3)^6(x-2)^6(x^2+9))

expand

\frac{x ^{3} - 4 x ^{2} + 2 x + 5}{x ( x + 3 ) ^{6} ( x - 2 ) ^{6} ( x ^{2} + 9 )}

\frac{x ^{3} - 4 x ^{2} + 2 x + 5}{x ^{15} + 6 x ^{14} - 12 x ^{13} - 106 x ^{12} + 6 x ^{11} + 366 x ^{10} + 496 x ^{9} + 5418 x ^{8} - 4311 x ^{7} - 62964 x ^{6} + 35964 x ^{5} + 264384 x ^{4} - 198288 x ^{3} - 419904 x ^{2} + 419904 x}

Solution steps

\frac{x ^{3} - 4 x ^{2} + 2 x + 5}{x ( x + 3 ) ^{6} ( x - 2 ) ^{6} ( x ^{2} + 9 )}

(x + 3)^{6} = x^{6} + 18 x^{5} + 135 x^{4} + 540 x^{3} + 1215 x^{2} + 1458 x + 729

= \frac{x ^{3} - 4 x ^{2} + 2 x + 5}{x ( x ^{6} + 18 x ^{5} + 135 x ^{4} + 540 x ^{3} + 1215 x ^{2} + 1458 x + 729 ) ( x - 2 ) ^{6} ( x ^{2} + 9 )}

(x - 2)^{6} = x^{6} - 12 x^{5} + 60 x^{4} - 160 x^{3} + 240 x^{2} - 192 x + 64

= \frac{x ^{3} - 4 x ^{2} + 2 x + 5}{x ( x ^{6} + 18 x ^{5} + 135 x ^{4} + 540 x ^{3} + 1215 x ^{2} + 1458 x + 729 ) ( x ^{6} - 12 x ^{5} + 60 x ^{4} - 160 x ^{3} + 240 x ^{2} - 192 x + 64 ) ( x ^{2} + 9 )}
