5+(19)/z = 4/(z^2)

5 + \frac{19}{z} = \frac{4}{z ^{2}}

z = \frac{1}{5}, z = - 4

Decimal Notation

z = 0.2, z = - 4

Solution steps

5 + \frac{19}{z} = \frac{4}{z ^{2}}

Multiply by LCM

5 z^{2} + 19 z = 4

Solve

5 z^{2} + 19 z = 4 : z = \frac{1}{5}, z = - 4

z = \frac{1}{5}, z = - 4

Verify Solutions

Find undefined (singularity) points:

z = 0

Combine undefined points with solutions:

z = \frac{1}{5}, z = - 4

\frac{( 7.6 - 2 x ) ^{2}}{x} = 0.722

\frac{3 + x}{5 + x} = \frac{9}{10}

\frac{x}{x - 3} = - 1.5

\frac{1}{x} = 0.0625

\frac{3}{15} = \frac{1.4}{a}
