Warm Up Math III 10/11/12Find the following using long division:
Remainder Theorem If a polynomial f(x) is divided by (x-r) and a
remainder of R is obtained, then f(r) = R.
Example: Use the remainder theorem to find the remainder of the following equation:
Since we are dividing by , we set x – 2 = 0 and solve. Therefore, x = 2.
Now, plug
Rational Root Theorem
If a polynomial has rational roots then p is a factor of and is a factor of
Rational Root Theorem
To find the possible roots of a polynomial:1. Find all factors of the leading coefficient (called
q)2. Find all factors of the last term, the one with no
variable (called p)3. Divided each p by each q.
Example: List all possible rational roots of
