\frac{- x ^{3} + 4 x}{x ^{2} - 9} = 4 x

x = 0, x = - 22, x = 22

Decimal Notation

x = 0, x = - 2.82842 \dots, x = 2.82842 \dots

Solution steps

\frac{- x ^{3} + 4 x}{x ^{2} - 9} = 4 x

Multiply both sides by

x^{2} - 9

- x^{3} + 4 x = 4 x (x^{2} - 9)

Solve

- x^{3} + 4 x = 4 x (x^{2} - 9) : x = 0, x = - 22, x = 22

x = 0, x = - 22, x = 22

Verify Solutions

Find undefined (singularity) points:

x = 3, x = - 3

Combine undefined points with solutions:

x = 0, x = - 22, x = 22

\frac{6}{x - 1} = \frac{9}{7}

y, \frac{y}{y + 1} = x

\frac{15}{2 g - 7} = \frac{3}{5}

\frac{5}{x} = - \frac{3}{x + 4}

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