The standard form of a quadratic is a² bx c 0. Here D sqrtb2 4ac sqrt-3 Hence the equation has complex roots given by. It tells the nature of the roots.
X2 3 x 3.
D 14 2 4 1 45 16. X b b 2 4 a c 2 a. Imaginary or complex roots will occur when the value under the radical portion of the quadratic formula is negative. The discriminant b 2 4 a c 0 so there are two complex roots.
