  Polynomials and Partial Fractions
  F(a) = (x-a)Q(x) + R
  If F(a) = 0, then (x-a) is a factor because F(a)=(a-a)•Q'(x)=0•Q'(x)=0
  Practice one or two can liao.
  
  Partial Fractions
  Know what each denominator leads to what numerators
  (x+k) leads to A/(x+k)
  (x²+k) leads to (Bx+C)/(x²+k)
  (x+k)² leads to two parts A/(x+k) and B/(x+k)²
  (x+k)³ leads to three parts A/(x+k), B/(x+k)² and C/(x+k)³
  (x+k)^n leads to n parts
  
  Compare their coefficients and form equations to solve.

  Identities:
  
  1. Memorise the tables, but I must say, practice makes u remember them much better. Especially multiple angle questions!
  2. LHS=RHS, you can work from RHS or use pencil and try to find a midpoint linking the two

  erm,
  if i have a numerator of Ax² + Bx + C
  i need to reduce it to at least Bx + C right?

  Yes. Or simply simplify and take out a number? But a pure partial fractions qn wun ask that.
  
  A irreducible denominator of Ax²+Bx+C will mean a numberator of Bx+C.
