Given that the quotient of dividing f(x) by (x-3) , the results
will be x^2 + 3x -5 and remainder of 2:
Then f(x) is a product of
two functions, including (x-3), plus two.
==> f(x) =
(x-3)*R(x) + 2
Let us write :
f(x) /
(x-3) = (x^+ 3x -5) + 2
We will multiply by
(x-3).
==> f(x) = (x-3)(x^2 +3x -5) +
2
Now to find f(3) we will substitute with x= 3
:
f(3) = (3-3)( 3^2 + 3&3 -5) +
2
==> f(3) = 0 + 2 = 2
Then, we
know that:
f(3) =
2
