simplify ((15)/(s+1)+35s-21)(s^2+3)

simplify

(\frac{15}{s + 1} + 35 s - 21) (s^{2} + 3)

\frac{( 35 s ^{2} + 14 s - 6 ) ( s ^{2} + 3 )}{s + 1}

Solution steps

(\frac{15}{s + 1} + 35 s - 21) (s^{2} + 3)

Join

\frac{15}{s + 1} + 35 s - 21 : \frac{35 s ^{2} + 14 s - 6}{s + 1}

= \frac{35 s ^{2} + 14 s - 6}{s + 1} (s^{2} + 3)

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{( 35 s ^{2} + 14 s - 6 ) ( s ^{2} + 3 )}{s + 1}

\frac{s + 2}{s ( s + 3 ) ( s + 1 )}

(- 1 + e^{- \frac{x}{Bw}}) (e^{- \frac{1}{A}} - 1)

7 cos (x^{3} - 2 x) (3 x^{2} - 2)

3 + 1

(e^{7 x} + e^{- 7 x}) (e^{7 x} - e^{- 7 x})
