4pir+2/(r^2)=0

4 π r + \frac{2}{r ^{2}} = 0

Solution steps

4 π r + \frac{2}{r ^{2}} = 0

Multiply both sides by

r^{2}

4 π r^{3} + 2 = 0

Find undefined (singularity) points:

r = 0

Combine undefined points with solutions:

\frac{9}{x + 1} = \frac{2}{x ^{2} - 1}

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

x, \frac{8}{x + 8} = \frac{7}{x + 4}

\frac{2}{( 1 - a )} = 3

y, \frac{3 y - 2 x}{2 y - 3 x} = 0
