0 = 2 x - \frac{128}{x ^{2}}

x = 4, x = - 2 + 23 i, x = - 2 - 23 i

Solution steps

0 = 2 x - \frac{128}{x ^{2}}

Multiply both sides by

x^{2}

0 = 2 x^{3} - 128

Solve

0 = 2 x^{3} - 128 : x = 4, x = - 2 + 23 i, x = - 2 - 23 i

x = 4, x = - 2 + 23 i, x = - 2 - 23 i

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = - 2 + 23 i, x = - 2 - 23 i

\frac{x ^{2} + 5 x + 6}{x + 3} = 0

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

14 = \frac{56}{x}

\frac{x + 6}{x + 3} = 2 - \frac{5 x + 12}{x + 3}

\frac{7}{x} - \frac{1}{3 x} = \frac{5}{3}
