Hi,
I'm having some difficulty writing the following as partial fractions (well, getting the answer the same as the Edexcel book)
a) (3x^2 +12x + 8) / ((x+2)^3)
b) (x^4) / (x^2 -2x +1)
Any help would be much appreciated-I know how to divide to stop the fraction being improper, but can't seem to do the repeated part ( as its x+2 cubed in (a) and x-1 squared in (b)
