\n" ); document.write( "12/sqrt(5x+6)=sqrt(2x+5)
\n" ); document.write( "sqrt[5x+6)(2x+5) = 12
\n" ); document.write( "10x^2+37x+30 = 12
\n" ); document.write( "10x^2 + 37x +18 = 0
\n" ); document.write( "------------

\n" ); document.write( "-------------
\n" ); document.write( "Only x= -0.57623 is an acceptable answer as the other makes the
\n" ); document.write( "original equation meaningless as it would involve sqrt(negative number)
