x+(12)/x =-7

x + \frac{12}{x} = - 7

x = - 3, x = - 4

Solution steps

x + \frac{12}{x} = - 7

Multiply both sides by

x

x^{2} + 12 = - 7 x

Solve

x^{2} + 12 = - 7 x : x = - 3, x = - 4

x = - 3, x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 3, x = - 4

\frac{x - 55}{x} = \frac{31}{100}

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

\frac{7}{4 x - 3} = \frac{2}{x + 3}

k, r = \frac{k}{k - 7}

- 6 + \frac{x}{x - 6} = \frac{1}{x - 6}
