u-12(u)^{-1}-1=0

u - 12 (u)^{- 1} - 1 = 0

u = 4, u = - 3

Solution steps

u - 12 u^{- 1} - 1 = 0

Refine

u - \frac{12}{u} - 1 = 0

Multiply both sides by

u

u^{2} - 12 - u = 0

Solve

u^{2} - 12 - u = 0 : u = 4, u = - 3

u = 4, u = - 3

Verify Solutions

Find undefined (singularity) points:

u = 0

Combine undefined points with solutions:

u = 4, u = - 3

- \frac{8}{( x - 2 ) ^{2}} = - 2

\frac{a}{a - 1} = - \frac{4}{3}

\frac{4 x - 6}{x - 7} = \frac{1}{2}

2 = - 6 + \frac{8}{x ^{2}}

\frac{4}{x} = \frac{7}{3}
