5/(x^2)-(43)/x =18

\frac{5}{x ^{2}} - \frac{43}{x} = 18

x = \frac{1}{9}, x = - \frac{5}{2}

Decimal Notation

x = 0.11111 \dots, x = - 2.5

Solution steps

\frac{5}{x ^{2}} - \frac{43}{x} = 18

Multiply by LCM

5 - 43 x = 18 x^{2}

Solve

5 - 43 x = 18 x^{2} : x = \frac{1}{9}, x = - \frac{5}{2}

x = \frac{1}{9}, x = - \frac{5}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{1}{9}, x = - \frac{5}{2}

- \frac{4 x}{x + 3} + 8 x = 7

\frac{3}{x - 9} + 1 = \frac{4 x}{x - 9}

2 x - \frac{400}{x ^{2}} = 0

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

\frac{1}{3 - x} = \frac{x ^{2} - 9}{( x - 3 ) ^{2}}
