The remainder theorem tells us the value of a polynomial when `x = a` is the remainder when the polynomial is divided by `x - a`.
We'll use synthetic division to divide by `(x - 4)`:
The last entry of the row is the remainder, `6`.
So the value of `x^3+6 x^2-30 x-34` when `x = 4` is `6`.
We'll use synthetic division to divide by `(x - 4)`:
| `4` | `1` | `6` | `-30` | `-34` |
| `4` | `40` | `40` | ||
| `1` | `10` | `10` | `6` |
The last entry of the row is the remainder, `6`.
So the value of `x^3+6 x^2-30 x-34` when `x = 4` is `6`.
