roots 1-1/(x^2)

roots

1 - \frac{1}{x ^{2}}

x = 1, x = - 1

Solution steps

1 - \frac{1}{x ^{2}}

The roots are the intercepts with the x-axis

(y = 0)

1 - \frac{1}{x ^{2}} = 0

Multiply both sides by

x^{2}

x^{2} - 1 = 0

Solve

x^{2} - 1 = 0 : x = 1, x = - 1

x = 1, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = - 1

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

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

\frac{x ^{2}}{3 - x} = \frac{2 x}{3 - x}

\frac{x}{x + 1} + 6 = \frac{1}{x ^{2} + x}

9 x + 1 = \frac{8}{x}
