expand ((z+J^2)(z-14)5)/(z-14+J^2)

expand

\frac{( z + J ^{2} ) ( z - 14 ) 5}{z - 14 + J ^{2}}

\frac{5 z ^{2} - 70 z + 5 z J ^{2} - 70 J ^{2}}{z - 14 + J ^{2}}

Solution steps

\frac{( z + J ^{2} ) ( z - 14 ) \cdot 5}{z - 14 + J ^{2}}

Expand

(z + J^{2}) (z - 14) \cdot 5 : 5 z^{2} - 70 z + 5 z J^{2} - 70 J^{2}

= \frac{5 z ^{2} - 70 z + 5 z J ^{2} - 70 J ^{2}}{z - 14 + J ^{2}}

(x - cos (\frac{2 π}{7})) (x - cos (\frac{4 π}{7})) (x - cos (\frac{6 π}{7}))

(- e^{t} sin (t) + e^{t} cos (t))^{2} + cos^{2} (t)

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

\frac{( a s + 1 )}{s ^{2} ( b s + 1 )}

\frac{1}{4} (5 - 2 x) (3 + 2 x)
