Algebra.Com's Answer #322239 by ccs2011(207)![]() ![]() You can put this solution on YOUR website! The discriminant, D is as follows: \n" ); document.write( "given quadratic equation \n" ); document.write( "D = \n" ); document.write( "If D = 0, then there is only 1 real solution, specifically x = -b/2a \n" ); document.write( "If D > 0, then there are exactly 2 real solutions \n" ); document.write( "If D < 0, then no real solutions exist, graph never crosses x-axis \n" ); document.write( "For this equation \n" ); document.write( "a = 5 \n" ); document.write( "b = -3 \n" ); document.write( "c = 1 \n" ); document.write( "D = \n" ); document.write( "-11 < 0 \n" ); document.write( "Therefore, no real solutions exist for this equation \n" ); document.write( " |
