this question should be under Add Maths rather than E Maths.
the question will be a bit hard to do with just the formulas taught in O level A Maths. much easier if can apply factor formulas from A level H1/H2 Maths.
note that the factor formulas can be derived from the sum & difference formulas taught in O level A Maths.

if strictly rely on formulas taught in O level A Maths, probably looking at splitting 5A & 3A using sum & difference formulas and double angle formulas, ... likely quite tedious work involved.
