Quizplus · Accepted Answer

To solve the equation, multiply through by $x^2$ to clear the fractions: $x^2 + x = 20$. Rearrange to form a quadratic equation: $x^2 + x - 20 = 0$. Factor the quadratic: $(x - 4)(x + 5) = 0$. The solutions are $x = 4$ and $x = -5$.

Solve the Equation 1+1x=20x21 + \frac { 1 } { x } = \frac { 20 } { x ^ { 2 } }1+x1​=x220​

Solve the Equation $1 + \frac { 1 } { x } = \frac { 20 } { x ^ { 2 } }$
