Partial Fractions – Algebraic Decomposition

Medium

It is given that there exist constants AA and BB such that

x3+8x2+12x+20=A(x+1)(x2+4)+B(x2+4)+4(x+1)2x^3 + 8x^2 + 12x + 20 = A(x + 1)(x^2 + 4) + B(x^2 + 4) + 4(x + 1)^2

for all xRx \in \mathbb{R}. Find the values of AA and BB. Hence, write down

x3+8x2+12x+20(x+1)2(x2+4)\frac{x^3 + 8x^2 + 12x + 20}{(x + 1)^2(x^2 + 4)}

in partial fractions.

A quadratic polynomial G(x)G(x) has remainders 13\frac{1}{3}, 15\frac{1}{5}, and 18\frac{1}{8} when divided by (x1)(x - 1), (x3)(x - 3), and (x6)(x - 6) respectively. Show that (x1)(x - 1), (x3)(x - 3), and (x6)(x - 6) are factors of the polynomial

f(x)=(x+2)G(x)1f(x) = (x + 2)G(x) - 1

Hence, find f(x)f(x)
