You can put this solution on YOUR website!
Since division by zero is not allowed, we must make sure that the denominator $\"2x\"$ is not equal to zero. If it is, then $\"2x=0\"$ means that $\"x=0\"$ . So if $\"x=0\"$ , then the denominator is zero (which is not allowed). So when $\"x=0\"$ , the rational expression $\"-3%2F%282x%29\"$ is not defined. \n" ); document.write( "
