For a quadratic equation, \(ax^2+bx+c=0\)

If we have two roots x1 and x2,

x1+x2 = \(-\frac{b}{a}\) and x1*x2 = \(\frac{c}{a}\)

We have been asked to find the value of x1*x2.

Given data: quadratic equation in hand that a=1

Coming to the statements :

1) One of the roots is 3.

Knowing one of the roots is not going to be enough, as the other root

can be any number and therefore, the product of the roots will be

different for every different value of the second root(Insufficient)

2) c=6

If a=1, the product of the roots is also c which is 6(Sufficient)

(Option B)
