1. Let f(x) be a polynomial with real coefficients
It is given that the leading coefficient of f(x) is 2 and deg f(x) = 4
When f(x) is divided by (x + 2) , the remainder is -28
When f(x) is divided by (x^2 - 1) , the remainder is (13x + 1)
Let r(x) be the remainder when f(x) is divided by (x + 2)(x^2 - 1)
(a)Find r(x)
(b)If f(x) is divisible by (x - 2) , find f(x)
原來還有(b)..
