x + \frac{4}{x} = 12

x = 2 (3 + 22), x = 2 (3 - 22)

Decimal

x = 11.65685 \dots, x = 0.34314 \dots

Solution steps

x + \frac{4}{x} = 12

Multiply both sides by

x

x^{2} + 4 = 12 x

Solve

x^{2} + 4 = 12 x : x = 2 (3 + 22), x = 2 (3 - 22)

x = 2 (3 + 22), x = 2 (3 - 22)

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2 (3 + 22), x = 2 (3 - 22)

\frac{6}{x + 1} = \frac{x}{x - 1}

\frac{5 x + 4}{x + 2} = \frac{8 + 4 x}{x - 3}

\frac{x ^{2}}{16} = 1 + \frac{\frac{3}{4 x}}{9}

y, - \frac{y}{x} = - 1

\frac{6}{x} = x - 5
