## Precalculus (6th Edition)

$0$ cannot be a solution of the given equation.
RECALL: The denominator of a rational expression is not allowed to be equal to zero. To find the numbers that will make the denominator equal to zero, equate each denominator to zero then solve each equation to obtain: \begin{array}{ccc} &2x=0 &\text{or} &x=0 \\&x=0 &\text{or} &x=0 \end{array} Thus, $0$ is not possible solution to the given equation.
