Expand the numerator: $$ (2x^2 - 8x + x - 4) - (x^2 - 3x + 2x - 6) \le 0 $$ $$ (2x^2 - 7x - 4) - (x^2 - x - 6) \le 0 $$ $$ x^2 - 6x + 2 \le 0 $$

The 2012 National Junior College (NJC) H2 Mathematics Preliminary Examination remains a benchmark paper for students preparing for the Singapore-Cambridge GCE A-Level H2 Mathematics (Syllabus 9758). Known for its conceptual depth and demanding algebraic manipulation, this paper serves as an excellent diagnostic tool.

The paper is lengthy. The "show" questions (Prove that...) are designed to be quick if you know the trick, and time-sinks if you don't. If you are stuck on a proof for more than 5 minutes, move on. The subsequent marks are often independent.

: Often involving normal distributions or testing population means. Expand the numerator: $$ (2x^2 - 8x +
