Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{4}{5}

\frac{x ^{2} - 4 x}{( x - 2 ) ^{2}} = 0

\frac{5}{x + 2} + \frac{3}{5 x + 3} = 0

\frac{- 2 x ^{2} + 5 x - 1}{2 x - 1} = 0

\frac{5 x}{x + 2} = \frac{3 x}{x + 1}

\frac{34}{x} = \frac{17}{2}
