z+9/z= -10
\n" ); document.write( "(z*z+9)/z=-10
\n" ); document.write( "(z^2+9)/z=-10 cross multiply.
\n" ); document.write( "z^2+9=-10z
\n" ); document.write( "z^2+10z+9=0
\n" ); document.write( "(z+9)(z+1)=0
\n" ); document.write( "z+9=0
\n" ); document.write( "z=-9 ans.
\n" ); document.write( "z+1=0
\n" ); document.write( "z=-1 ans.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
