if p and q are the roots of the equation x2 - px + q = 0 then :
A) p = 1, q = -2

B) p = 0, q = 1

C) p = -2, q = 0

D) p = -2, q = 1

The given quadratic equation is

Here, a = 1, b = – p and c = q.

p and q are roots of the given quadratic equation.

∴ Sum of the roots = p + q =

q = pp = 0

Product of the roots = pq =

∴  pq = q

p = 1

Thus, the value of p and q is 1 and 0 respectively.
