((x-1)(2x+84))/x-84=0

\frac{( x - 1 ) ( 2 x + 84 )}{x} - 84 = 0

x = 7, x = - 6

Solution steps

\frac{( x - 1 ) ( 2 x + 84 )}{x} - 84 = 0

Multiply both sides by

x

(x - 1) (2 x + 84) - 84 x = 0

Solve

(x - 1) (2 x + 84) - 84 x = 0 : x = 7, x = - 6

x = 7, x = - 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 7, x = - 6

x^{4} + \frac{1}{x ^{4}} = 47

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

x^{- 2} - 5 x^{- 1} - 6 = 0

\frac{4}{x} - \frac{9}{x + 1} = 2

41 y^{- 4} - 58 y^{- 2} + 1 = 0
