(x^2+1)/((x^2)-5(x+1/x)+8)=0

\frac{x ^{2} + 1}{( x ^{2} ) - 5 ( x + \frac{1}{x} ) + 8} = 0

x = i, x = - i

Solution steps

\frac{x ^{2} + 1}{( x ^{2} ) - 5 ( x + \frac{1}{x} ) + 8} = 0

Simplify

\frac{x ^{2} + 1}{( x ^{2} ) - 5 ( x + \frac{1}{x} ) + 8} : \frac{x ^{2} + 1}{x ^{2} - 5 ( x + \frac{1}{x} ) + 8}

\frac{x ^{2} + 1}{x ^{2} - 5 ( x + \frac{1}{x} ) + 8} = 0

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

x^{2} + 1 = 0

Solve

x^{2} + 1 = 0 : x = i, x = - i

x = i, x = - i

1 = \frac{1.5 h}{800 + h}

\frac{x ^{2} + 1}{x ^{2} - 5 ( x + \frac{1}{x} ) + 8} = 0

\frac{x + 1}{x} = \frac{21}{20}

x x^{3} + \frac{\frac{x}{1}}{\frac{5}{x}} = \frac{9}{10}

g = \frac{10 m}{s ^{2}}
