Algebra.Com's Answer #293912 by ilana(307)![]() ![]() ![]() You can put this solution on YOUR website! For an equation Ax^2 + Bx + C = 0, the discriminant is the value B^2 - 4AC. \n" ); document.write( "If the discriminant is a positive number, there are 2 real solutions. \n" ); document.write( "If the discriminant is a negative number, there are 2 imaginary solutions. \n" ); document.write( "If the discriminant is 0, there is 1 real solution. \n" ); document.write( "If you calculate the discriminant here (I'll leave that for you to do), you should get a positive number, so the answer is A. \n" ); document.write( " |
