I would like to add that, with 20 being the remainder, if you remember the long division, there were 3 different ways you could express the remainder: 1) as a decimal, 2) as a fraction, or 3) with R then the number after it. For polynomials, #1 isn't used. For the other two, though, it could depend upon how your teacher would want the remainder expressed. For, if as a fraction, the remainder would be shown as:
Good luck, xata. I hope this helps.
For any polynomial P(x), the remainder when it is divided by (x - a) is equal to P(a).
When the polynomial P(x) = 3x^4 - 8x^2 + 3x - 2 is divided by (x - 2), the remainder is P(2) = 3*2^4 - 8*2^2 + 3*2 - 2 = 20
The remainder when 3x^4 - 8x^2 + 3x - 2 is divided by (x - 2) is 20
