(i) If x = -m/l is a zero of polynomial p(x) = lx + m, then p(-m/l) should be .
Here, p(-m/l) = l(-m/l) + m
= m + m = 0
Therefore, x = -m/l is a zero of the given polynomial.
(ii) If x = 0 is a zero of polynomial p(x) = x2, then p(0) should be zero. Here, p(0) = (0)2 = 0
Hence, x = 0 is a zero of the given polynomial.
