expand 1/((s+7)(s-5)(s+12))

expand

\frac{1}{( s + 7 ) ( s - 5 ) ( s + 12 )}

\frac{1}{s ^{3} + 14 s ^{2} - 11 s - 420}

Solution steps

\frac{1}{( s + 7 ) ( s - 5 ) ( s + 12 )}

Expand

(s + 7) (s - 5) (s + 12) : s^{3} + 14 s^{2} - 11 s - 420

= \frac{1}{s ^{3} + 14 s ^{2} - 11 s - 420}

(x + \frac{1}{x})^{2} (x + \frac{1}{x})

\frac{d ^{2}}{d x ^{2}} ((x) (5 \cdot x^{3} - 2 \cdot x^{2} + 2 \cdot x))

\frac{( 1 - j ^{2} ) e ^{(0.5 - j^{1.047})}}{( 3 - j ^{4} )}

\frac{2}{( x - 5 ) ^{6}}

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