Find the zero of the polynomial in each of the following cases.
f(x) = px + q, p ≠ 0, p q are real numbers.

f(x) = px + q, p ≠ 0, p q are real numbers.

f(x) = 0

⇒ px + q = 0

⇒ px = -q

∴ is the zero of the polynomial px + q.

Find the zero of the polynomial in each of the following cases.

f(x) = x²

Find the zero of the polynomial in each of the following cases.

f(x) = px, p ≠ 0
