To find the value of
such that \( P(x) = x^4 - 2x^3 + kx - 4 \) has a remainder of 0 when divided by \( (x-1) \), we can use the Remainder Theorem. According to the Remainder Theorem, if a polynomial \( P(x) \) is divided by \( (x-a) \), the remainder is \( P(a) \).In this case, we are dividing \( P(x) \) by \( (x-1) \), so we need to evaluate \( P(1) \) and set it equal to 0.
Since the remainder is 0, we have:
Solving for
, we get:
Therefore, the value of
is
