2. Express (16-4x) in the form a(1+bx), where a and b are real numbers. Find the values of a and b. The binomial expansion (16-4x) in ascending powers of x up to the term in x' is 64+cx+da+ex' +..., find the values of c, d and e. State the interval of x for which the expansion is valid. Hence, by substituting x=2 into the expansion, show that V2 is approximately equal to 64 45 [12 marks)
