k+(12)/k =8

k + \frac{12}{k} = 8

k = 6, k = 2

Solution steps

k + \frac{12}{k} = 8

Multiply both sides by

k

k^{2} + 12 = 8 k

Solve

k^{2} + 12 = 8 k : k = 6, k = 2

k = 6, k = 2

Verify Solutions

Find undefined (singularity) points:

k = 0

Combine undefined points with solutions:

k = 6, k = 2

\frac{- 15}{4 x + 1} = x - 4

\frac{( 4 x - 1 ) ( 2 x + 3 )}{18 x - 4} = 0

x + \frac{1}{x} = 3

\frac{1}{1 + x ^{2}} = 0

\frac{2}{x} = \frac{10}{25}
