[S2_20150519XFCH] Chunking for Factorisation
This is a question on factorisation (Am: factoring). The key to doing this is chunking. Can you see any chunk (maybe hidden) that is being repeated? Take this out as the common factor and simplify. Remember the square-of-differenceidentity (a – b)2 = a2 – 2ab + b2 .
As in this question, chunking is a very powerful tactic. When you attempt to solve mathematics problems, open your eyes wide!
H04. Look for pattern(s)
H10. Simplify the problem
H11. Solve part of the problem
H13* Use Equation / write a Mathematical Sentence
* Lower Secondary Mathematics (usually secondary 2 ~ grade 8 approx.)
* other syllabuses that involve algebraic factorisation and expansion
