x + 2 = \frac{4}{x}

x = 2, x = - 22

Decimal Notation

x = 1.41421 \dots, x = - 2.82842 \dots

Solution steps

x + 2 = \frac{4}{x}

Multiply both sides by

x

x^{2} + 2 x = 4

Solve

x^{2} + 2 x = 4 : x = 2, x = - 22

x = 2, x = - 22

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 22

\frac{x}{3} = \frac{9}{x + 5 x ^{2}}

\frac{8}{a} = \frac{21}{42}

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

\frac{- 3}{2 x} + \frac{6}{x} = - 9

\frac{1}{x ^{2} + 2} = \frac{1}{4}
