y + \frac{1}{y} - 22 = 0

y = 2 + 1, y = 2 - 1

Decimal Notation

y = 2.41421 \dots, y = 0.41421 \dots

Solution steps

y + \frac{1}{y} - 22 = 0

Multiply both sides by

y

y^{2} + 1 - 22 y = 0

Solve

y^{2} + 1 - 22 y = 0 : y = 2 + 1, y = 2 - 1

y = 2 + 1, y = 2 - 1

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 2 + 1, y = 2 - 1

\frac{3}{9} = \frac{3}{x + 2}

(- \frac{1}{2 x})^{2} = 16

x, z = \frac{m}{x y}

- \frac{2 x}{2 y} = - \frac{x}{y}

\frac{4 x ^{2} - 9}{x} = 5
