Question

If p,q are the roots of a quadratic equation ax2+bx+c, then what is value of (a)×(p)×(q)


  1. c

  2. a

  3. -b

  4. b


Solution

The correct option is A

c


We know that if quadratic equation is given in form ax2+bx+c

Then sum of the roots of the equation is (b)a

Product of roots of the equation is ca

 Here we have been asked to find the value of (a)×(p)×(q)

We know pq=ca

So (a)×(p)×(q) = c
