Algebra.Com's Answer #213211 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! if a>0 then x^2=-a then x would be an imaginary number \n" ); document.write( "so a is not greater than 0 \n" ); document.write( "if a-=0 then x=0 also \n" ); document.write( "that is possible \n" ); document.write( "if a<0 then the -a= is a positive number this could be \n" ); document.write( "so (E) II and III only \n" ); document.write( " |
