You can put this solution on YOUR website!
I assume the denominator is $\"a%5E2%2B2a-3\"$
\n" ); document.write( ":
\n" ); document.write( "if so $\"a%5E2%2B2a-3\"$ cannot =0 or equation would be undefined
\n" ); document.write( ":
\n" ); document.write( "so set $\"a%5E2%2B2a-3=0\"$
\n" ); document.write( ":
\n" ); document.write( " $\"%28a%2B3%29%28a-1%29=0\"$
\n" ); document.write( ":
\n" ); document.write( "so if a were -3 or 1 the equation would be undefined....therefore a=-3,1 are excluded values for a \n" ); document.write( "
