1-(16)/(x^2)=0

1 - \frac{16}{x ^{2}} = 0

x = 4, x = - 4

Solution steps

1 - \frac{16}{x ^{2}} = 0

Multiply both sides by

x^{2}

x^{2} - 16 = 0

Solve

x^{2} - 16 = 0 : x = 4, x = - 4

x = 4, x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4, x = - 4

x, y = \frac{x + 2}{x - 1}

\frac{x - 7}{x + 9} = \frac{1}{x - 2}

\frac{5}{2 y} = \frac{10}{5 y - 8}

\frac{x - 2}{x - 6} = - \frac{4}{x}

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