-1/(X^2)=-1/9

- \frac{1}{X ^{2}} = - \frac{1}{9}

X = 3, X = - 3

Solution steps

- \frac{1}{X ^{2}} = - \frac{1}{9}

Cross multiply

- 9 = - X^{2}

Solve

- 9 = - X^{2} : 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{8}{y})^{3} - 8 = 0

\frac{6}{x} = \frac{14}{35}

\frac{x + 52}{11 - x} = \frac{5}{2}

x 898.47 = \frac{1000}{1 + x ^{2}}

\frac{0.2 + x}{( 2 - 2 x ) ^{2}} = 0.078
