((-0.2x^2+20))/(x^2)=0

\frac{( - 0.2 x ^{2} + 20 )}{x ^{2}} = 0

x = 10, x = - 10

Solution steps

\frac{( - 0.2 x ^{2} + 20 )}{x ^{2}} = 0

Simplify

\frac{( - 0.2 x ^{2} + 20 )}{x ^{2}} : \frac{- 0.2 x ^{2} + 20}{x ^{2}}

\frac{- 0.2 x ^{2} + 20}{x ^{2}} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

- 0.2 x^{2} + 20 = 0

Solve

- 0.2 x^{2} + 20 = 0 : x = 10, x = - 10

x = 10, x = - 10

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 10, x = - 10

\frac{3 x}{x + 52} = 19.6

\frac{3}{2 x} = 6

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

\frac{t}{t - 1} = \frac{2}{t - 1} + 2
