Tip of the Day If the remainder when a polynomial f(x) is divided by binomial of the form (x – a) is R, then f(a) = R. This is also called the Polynomial Remainder Theorem.
Also, if (x – a) is a factor of f(x), then a will be a root of f(x). This is because, if (x – a) completely divides f(x) without leaving any remainder, then R = 0, and so f(a) = 0. Last year's Question of the day (29-Sep-11) In Δ ABC, AD is drawn parallel to BC such that AD = BC. BD meets AC at O and OA = OD = 10 cm. AB = 16 cm
Find BC.
