Best ResponseYou've already chosen the best response.0The general form of a quadratic equation is ax^2 + bx + c = 0 where a, b and c are numbers. There is a formula for the roots and that is( b+ sqrt(b^24ac) / 2a The disvriminant is b^24ac. If discriminant is > 0 there are two real roots, if equal to 0 there are two equal real roots and if it is < 0 then the roots are imaginary.

Best ResponseYou've already chosen the best response.0eg solve x^2 + 5x + 13 = 0 Discriminant = 5^2  4*1* 13 = 27 the sqrt of 27 is imaginary no real roots
