How do you express #(x^3+4)/[x^2+4] # in partial fractions? Precalculus Matrix Row Operations Partial Fraction Decomposition (Linear Denominators) 1 Answer George C. May 13, 2016 #(x^3+4)/(x^2+4) = x-(4x-4)/(x^2+4)# Explanation: #(x^3+4)/(x^2+4) = (x^3+4x-4x+4)/(x^2+4) = x-(4x-4)/(x^2+4)# The denominator #(x^2+4)# has no linear factors with Real coefficients since #x^2+4 >= 4 > 0# for all Real values of #x#.
