多项式函数的问题~!数学高手帮帮忙解决~!
在多项式函数 P(x) 除 (x+1), 余数会是4.如果 P(x) 除以 (x-2), 余数会是3. 那么 P(X) 除 x^2-x-2, 余数会是多少?
原题为:
When polynomial function P(X) is divided by (X-1) the remainder is 4 and when it is divided by (X-2) the remainder is 3. what is the remainder when P(X) is divided by X^2-X-2?

Answer 1

就是P(X)除以(X+1)(X-2),余2X+6
