Question




Solution


Comment
     Note in the above working that  3(x + kx2)2 = 3(x2 + 2kx3 + k2x4),  but since we do not need the  x3  and  x4  terms, we omit them and just write “3(x2 + ... )”.


H12* Think of a related problem
H13* Use Equation / write a Mathematical Sentence

Suitable Levels
* revision for GCE ‘A’ Level H2 Mathematics
* AP Calculus
* other syllabuses infinite binomial series
