WebIf two polynomials p (x) = 0 and q (x) = 0 have a common root α, then p (α) = q (α) = 0. Calculation: Let's say that the common root between p (x) = x 2 + ax + b = 0 and q (x) = x 2 + bx + a = 0 is α. Then, we must have p (α) = q (α) = 0. ⇒ α 2 + aα + b = α 2 + bα + a = 0 ⇒ aα - bα + b - a = 0 ⇒ α (a - b) - (a - b) = 0 ⇒ (a - b) (α - 1) = 0
