Question

write an algorithm to find out the discriminant of a

quadratic equation​

Answer 1

Answer:

k)/ 2a and r2 =(b + i? k)/ 2a are the two roots. For example, consider the following equation 2x^2 8x + 3 = 0. a = 2, b = -8, c = 3  Discriminant value, k =b^2 - 4ac = 8^2 - 4*(-8)*3  = 40  The discriminant value is positive.

Answer 2

Answer:

d = b^2+4ac

d=0 ,2 real and equal roots

d is less than 0 than 2 real and distinct roots
