(-4x)/((x^2-1)^2)=0

\frac{- 4 x}{( x ^{2} - 1 ) ^{2}} = 0

x = 0

Solution steps

\frac{- 4 x}{( x ^{2} - 1 ) ^{2}} = 0

Simplify

\frac{- 4 x}{( x ^{2} - 1 ) ^{2}} : - \frac{4 x}{( x ^{2} - 1 ) ^{2}}

- \frac{4 x}{( x ^{2} - 1 ) ^{2}} = 0

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

4 x = 0

Divide both sides by

4

x = 0

Verify Solutions

Find undefined (singularity) points:

x = 1, x = - 1

Combine undefined points with solutions:

x = 0

2 m^{- 2} = 32

x, f = \frac{3 x - 21}{x + 5}

\frac{28 x}{x - 1} = 336

\frac{2 + 8}{x} = 9

l, p = \frac{f}{π r l}
