x-(12)/x =1

x - \frac{12}{x} = 1

x = 4, x = - 3

Solution steps

x - \frac{12}{x} = 1

Multiply both sides by

x

x^{2} - 12 = x

Solve

x^{2} - 12 = x : x = 4, x = - 3

x = 4, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = - 3

\frac{1}{x} - \frac{1}{x ^{2}} = 0

\frac{3}{2 k} = 5

1 = \frac{8 x ^{2}}{x ^{4} + 16}

\frac{2 x - 1}{x + 2} = \frac{6}{5}

4 + (\frac{1}{x} - 2) = 20
