Find the discriminant of the quadratic equation 3x² – 5x – 11 = 0

Discriminant = b^2 - 4ac where a , b , c are compared values of the given equation with those of standard form of quadratic equation . So b = -5 , c= -11 and a = 3 put in values we get
 Discriminant = -5^2 - 4(3)(-11) = 25+132 = 157
