Algebra.Com's Answer #365237 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Use the discriminant to determine whether the following equations have solutions that are: two different rational solutions; two different irrational solutions; exactly one rational solution; or two different imaginary solutions. \n" ); document.write( "x^2 = -4x – 4 \n" ); document.write( "--- \n" ); document.write( "x^2 + 4x + 4 = 0 \n" ); document.write( "--- \n" ); document.write( "a = 1 ; b = 4 ; c = 4 \n" ); document.write( "---------------------------- \n" ); document.write( "Discriminant: b^2-4ac = 4^2-4*1*4 = 16 - 16 = 0 \n" ); document.write( "---- \n" ); document.write( "That means there is exactly one rational solution. \n" ); document.write( "========================================================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============ \n" ); document.write( " |
