Answer:
Explanation:
From the remainder theorem, we can get the remainder of a polynomial division by a linear polynomial.
All we have to do is to equate the linear polynomial to zero, then susbtitute the zero value into the polynomial. If the linear polynomial is a root, then zero will be the remainder, if not, we will have a value.
This is otherwise achievable by long division. This process is however more cumbersome and prone to error
The correct words to fill into the blank is thus; "Long"
