x + \frac{1}{x} - 8 = 0

x = 4 + 15, x = 4 - 15

Decimal Notation

x = 7.87298 \dots, x = 0.12701 \dots

Solution steps

x + \frac{1}{x} - 8 = 0

Multiply both sides by

x

x^{2} + 1 - 8 x = 0

Solve

x^{2} + 1 - 8 x = 0 : x = 4 + 15, x = 4 - 15

x = 4 + 15, x = 4 - 15

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4 + 15, x = 4 - 15

t, f = \frac{W - 2 t}{t k}

t, V = \frac{S}{t}

x + \frac{24}{x} = 11

- 0.84 = \frac{575000 - 562750}{x}

y, x = \frac{y - 6}{y}
