Math Problem Statement
Using the remainder theorem, find the remainder; when p(x) is divided by g(x), where p(x) = 3x4
- 6x2
- 8x - 2, g(x) = x - 2
Solution
The Remainder Theorem tells us that the remainder of a polynomial when divided by a linear divisor is simply .
In your case, the polynomial is being divided by . According to the Remainder Theorem, the remainder is , because implies .
Now, we can calculate :
Substitute into the polynomial:
Simplifying:
So, the remainder when is divided by is 6.
