TopicPolynomial Division & Manipulation
TypePolynomial Identity Matching
DifficultyModerate -0.8 This is a straightforward polynomial identity problem requiring coefficient matching. Students expand the right-hand side, collect like terms, and equate coefficients—a mechanical process with no conceptual difficulty. While it's FP1, this particular question is routine algebraic manipulation below average A-level difficulty.
Spec1.02j Manipulate polynomials: expanding, factorising, division, factor theorem

4 Find the values of \(A , B , C\) and \(D\) in the identity \(3 x ^ { 3 } - x ^ { 2 } + 2 \equiv A ( x - 1 ) ^ { 3 } + \left( x ^ { 3 } + B x ^ { 2 } + C x + D \right)\).

4 Find the values of $A , B , C$ and $D$ in the identity $3 x ^ { 3 } - x ^ { 2 } + 2 \equiv A ( x - 1 ) ^ { 3 } + \left( x ^ { 3 } + B x ^ { 2 } + C x + D \right)$.
