TopicFactor & Remainder Theorem
TypeSingle remainder condition to find constant
DifficultyModerate -0.8 This is a straightforward application of the remainder theorem requiring only direct substitution of x=2 into the polynomial and solving a simple linear equation. It's easier than average as it involves minimal steps and tests only basic recall of the theorem with no problem-solving complexity.
Spec1.02j Manipulate polynomials: expanding, factorising, division, factor theorem

4 When \(x ^ { 3 } + k x + 5\) is divided by \(x - 2\), the remainder is 3 . Use the remainder theorem to find the value of \(k\).
