TopicSolving quadratics and applications
TypeAlgebraic identity, find constants
DifficultyModerate -0.8 This is a straightforward algebraic identity problem requiring expansion and coefficient comparison. While it involves three unknowns, the method is mechanical (expand the right side, equate coefficients of x², x, and constants) with no conceptual difficulty or problem-solving insight needed. It's easier than average despite being FP1 because it's purely procedural algebra.
Spec1.02j Manipulate polynomials: expanding, factorising, division, factor theorem

2 Find the values of \(A , B\) and \(C\) in the identity \(2 x ^ { 2 } - 13 x + 25 \equiv A ( x - 3 ) ^ { 2 } - B ( x - 2 ) + C\).

2 Find the values of $A , B$ and $C$ in the identity $2 x ^ { 2 } - 13 x + 25 \equiv A ( x - 3 ) ^ { 2 } - B ( x - 2 ) + C$.
