Try another version of this question Get help: Box 1: Enter your answer as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4)
Enter DNE for Does Not Exist, oo for Infinity
We'll use synthetic division to divide by `x +5 = (x - (-5))`:
`-5`
`1`
`-6`
`-50`
`20`
`-5`
`55`
`-25`
`1`
`-11`
`5`
`-5`
The last entry of the row is the remainder, `-5`.
So the value of `x^3-6 x^2-50 x+20` when `x = -5` is `-5`.
