4x-(36)/x =0

4 x - \frac{36}{x} = 0

x = 3, x = - 3

Solution steps

4 x - \frac{36}{x} = 0

Multiply both sides by

x

4 x^{2} - 36 = 0

Solve

4 x^{2} - 36 = 0 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 3, x = - 3

\frac{x - 4}{x} + \frac{x ^{- 1}}{3} = - 2

\frac{2}{x} = \frac{8}{32}

- \frac{8}{y + 8} = - 5

x^{3} + \frac{27}{x ^{3}} = 28

\frac{1}{( x - 1 ) ^{2}} + \frac{3}{x - 1} - 10 = 0
