40x-(180)/(x^2)=0

40 x - \frac{180}{x ^{2}} = 0

Solution steps

40 x - \frac{180}{x ^{2}} = 0

Multiply both sides by

x^{2}

40 x^{3} - 180 = 0

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

\frac{x + 2}{x - 6} = - \frac{5}{x}

\frac{z ^{2} - 2 z - 4}{z} = 1

- \frac{6}{x + 1} + 6 = \frac{1}{x}

\frac{x - 6}{4 x} + 1 = \frac{x + 3}{x}

\frac{16}{x ^{2}} = \frac{50}{4}
