Question

give the formula for discriminant of quadratic equation bx² + cx + a =0,give the condition for the discriminant when the roots are (a)real and (b)roots are equal​

Answer 1

bx² + cx + a =0

condition for the discriminant when the roots are

(a)real

discriminant > 0

c²-4ab> 0

(b)roots are equal

discriminant =0

c²-4ab= 0
