1= 2/(x^2)-1/x

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

x = 1, x = - 2

Solution steps

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

Multiply by LCM

x^{2} = 2 - x

Solve

x^{2} = 2 - x : x = 1, x = - 2

x = 1, x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = - 2

X, 4 Y = \frac{3 X}{X + 1}

\frac{x}{0.1 - x} = 7.5

\frac{4}{x} = \frac{2}{5}

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

\frac{( x + 3 )}{x} = \frac{2}{5}
