expand (1+3x+x^2)/((x-19)(x-2)(x+6))

expand

\frac{1 + 3 x + x ^{2}}{( x - 19 ) ( x - 2 ) ( x + 6 )}

\frac{1 + 3 x + x ^{2}}{x ^{3} - 15 x ^{2} - 88 x + 228}

Solution steps

\frac{1 + 3 x + x ^{2}}{( x - 19 ) ( x - 2 ) ( x + 6 )}

Expand

(x - 19) (x - 2) (x + 6) : x^{3} - 15 x^{2} - 88 x + 228

= \frac{1 + 3 x + x ^{2}}{x ^{3} - 15 x ^{2} - 88 x + 228}

(x - 3 y) (x + 3 y)

α (2, 1, - 2)

\frac{k ( s + 1.5 )}{s ( s + 1 ) ( s + 10 ) + 1.5 k}

(x + i y - a - bi)^{2}

\frac{2 ( - 1 ) ^{k} + 3 ( - 1 ) ^{k - 1} + 2 \cdot 3 ^{k + 1} + 1}{2}
