الحلّ

expand

- \frac{4}{s ^{2} ( s ^{2} - 6 s + 9 )}

- \frac{4}{s ^{4} - 6 s ^{3} + 9 s ^{2}}

خطوات الحلّ

- \frac{4}{s ^{2} ( s ^{2} - 6 s + 9 )}

s^{2} (s^{2} - 6 s + 9)

وسٌع:

s^{4} - 6 s^{3} + 9 s^{2}

= - \frac{4}{s ^{4} - 6 s ^{3} + 9 s ^{2}}

1 + 1 + 4 (π^{2} + π)

\frac{x ( 6 x + 12 ) ( x - 2 ) ^{2}}{x - 3}

\frac{( e ^{t} + e ^{- t} ) e ^{t}}{2}

\frac{8}{6}

3 x^{2} \cdot (1 - 2 ln (x))
