What number should be added to 3x3 – 5x2 + 6x so that when resulting polynomial is divided by x – 3, the remainder is 8?
Let the numbw-er k be added and resulting polnomic be f(x).
So, f(x) =`3x^3+5x^2+6x+k`
it is given that when f(x)is dividing by (x-3), the remainder is 8.
Thus, the required number is -46.
