2k=(12)/k-5

2 k = \frac{12}{k} - 5

k = \frac{3}{2}, k = - 4

Decimal Notation

k = 1.5, k = - 4

Solution steps

2 k = \frac{12}{k} - 5

Multiply both sides by

k

2 k^{2} = 12 - 5 k

Solve

2 k^{2} = 12 - 5 k : k = \frac{3}{2}, k = - 4

k = \frac{3}{2}, k = - 4

Verify Solutions

Find undefined (singularity) points:

k = 0

Combine undefined points with solutions:

k = \frac{3}{2}, k = - 4

3 = \frac{5}{a x} + 5

4 x^{- 4} - 7 x^{- 2} - 2 = 0

\frac{7}{( 3 a + n )} = 2

V, D = \frac{M}{V}

x = \frac{15}{x} - 22
