When a polynomial \(f(x)\) is divided by \((x - 1) \)and \((x + 5)\), the remainders are -6 and 6 respectively. Let \(r(x)\) be the remainder when \(f(x)\) is divided by \(x^2 +4x - 5\). Find the value of \(r(-2)\).
(A) 0 (B) 1 (c) 2 (D) 3 (E) 5
How does one do this sort of question?
I'm not experienced with polynomials, so it may seem a simple question to you but not to me. But please help! I'm a learner too :)
