x+9/x =-10

x + \frac{9}{x} = - 10

x = - 1, x = - 9

Solution steps

x + \frac{9}{x} = - 10

Multiply both sides by

x

x^{2} + 9 = - 10 x

Solve

x^{2} + 9 = - 10 x : x = - 1, x = - 9

x = - 1, x = - 9

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 1, x = - 9

\frac{u + 2}{3 u - 1} + 1 = \frac{6 - u}{u + 1}

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

\frac{50}{x + 5} = \frac{x}{10} + 4.5

\frac{2}{x} + \frac{x + 6}{4} = 0

\frac{10000}{x} = 9
