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

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

x = 4, x = - 4

Solution steps

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

Move

1

to the left side

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

Multiply both sides by

x^{2}

- x^{2} = - 16

Solve

- x^{2} = - 16 : 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

2 + \frac{1149984}{x ^{3}} = 66

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

\frac{1}{x} + \frac{5}{x - 9} = 0

\frac{- 2}{3 x + 15} = - 20

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