x-4/x =0

x - \frac{4}{x} = 0

x = 2, x = - 2

Solution steps

x - \frac{4}{x} = 0

Multiply both sides by

x

x^{2} - 4 = 0

Solve

x^{2} - 4 = 0 : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 2

\frac{3 x}{6} = \frac{9}{2 x}

6 = a^{- 2} + 2

50 = \frac{f ^{6} - 1}{f - 1}

\frac{7}{8} = \frac{9}{x}

\frac{x - 2}{x + 2} = 0
