Question

If the discriminant of the quadratic equation
ax²+bx+c=0

is zero, then the roots of the equation​

Answer 1

Answer: Then the roots will be real and equal.

Step-by-step explanation:

Taking the equation:- ax²+bx+c=0

If b²- 4ac =0, then x= -b+-0/2a[applying the formula x=(b+- √b²-4ac)/2a]

(-b+- 0)/2a= -(b/2a), -(b/2a)

Thus, the roots of the equation ax²+bx+c=0 are both -(b/2a). That is we have two equal real roots
