Algebra.Com's Answer #454704 by tommyt3rd(5050)![]() ![]() You can put this solution on YOUR website! We can use the discriminant to determine the number and type of solutions: \r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since the discriminant is real and not 0 we know that there are 2 real solutions\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( ":) \n" ); document.write( " |
