If `x^2 - 8x + 15 = 0 and (x - 2)(x - p) = 0` and one root is common then p is

If the equation x^2 + px + q =0 and x^2 + p' x + q' =0 have common roots, show that it must be equal to (pq' - p'q)/(q-q') or (q-q')/(p'-p) .

IF x^2 +px + q=0 and x^2 + qx +p=0 have a common root , then their other roots are the roots of
