-1/(x^2)-2/(x^3)=0

- \frac{1}{x ^{2}} - \frac{2}{x ^{3}} = 0

x = - 2

Solution steps

- \frac{1}{x ^{2}} - \frac{2}{x ^{3}} = 0

Multiply by LCM

- x - 2 = 0

Move

2

to the right side

- x = 2

Divide both sides by

- 1

x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 2

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

\frac{- 54}{w} = 6

y, x = y^{- 3}

y, x = y^{- 2}

2 x - \frac{7}{x + 6} = x
