Best ResponseYou've already chosen the best response.2What do you mean? Set the discriminant to be greater than zero b^24ac > 0

Best ResponseYou've already chosen the best response.0if d > 0 then there are real and different roots d = 0 real and equal roots d < 0 imaginary roots

Best ResponseYou've already chosen the best response.0Real and different...? I'm guessing you mean real and distinct. But yes you can use the discriminant. When the discriminant is less than zero, it will have complex/imaginary roots, as the quadratic formula takes the square root of the discriminant ( http://www.purplemath.com/modules/quadform.htm ) \[3x^2+2x+3p=0 \]\[ax^2+bx+c = 0\] so here, a=3, b = 2 and c = 3p discriminant is \[b^24ac > 0 \]

Best ResponseYou've already chosen the best response.0If D>0 then sqrt(b^24ac) is a real number and roots are real and unequal

Best ResponseYou've already chosen the best response.0\[x = \frac{ b \pm \sqrt{b^2  4ac} }{ 2a }\] try putting different values of d and check out

Best ResponseYou've already chosen the best response.0as D>0 and D=b^24ac so, (2)^24*3*3p>0 436p>0 4>36p 1/9>0
