Data Sufficiency (DS) | Re: If m, n and p are constants and x^2 + mx + n = (x + p)^2 for all value

x^2 + mx + n = (x + p)^2

=> x^2 + mx + n = x^2 +2px +p^2
=> Comparing the coefficients we get, m = 2p and n =p^2

(1) p = 3
We can calculate value of n = p^2 = 9
Statement (1) alone is sufficient.
(2) m = 6
We can calculate value of m=2p => p =3 and n = p^2 = 9
Statement (2) alone is alsosufficient.
