c^{-2}= 1/4

c^{- 2} = \frac{1}{4}

c = 2, c = - 2

Solution steps

c^{- 2} = \frac{1}{4}

Refine

\frac{1}{c ^{2}} = \frac{1}{4}

Cross multiply

4 = c^{2}

Solve

4 = c^{2} : c = 2, c = - 2

c = 2, c = - 2

Verify Solutions

Find undefined (singularity) points:

c = 0

Combine undefined points with solutions:

c = 2, c = - 2

\frac{8}{10} = \frac{6}{x}

x, \frac{f - 8}{x - 1} = 10

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

b^{- 1} = 2.718 2^{2}

x + 4 = \frac{( x - 2 )}{x}
