How do you express #(2x^2+5)/(x^2+1)^2# in partial fractions?
Begin with the set up of the variables A, B, C, D
the LCD(Least common Denominator) is
so that the right side of the equation becomes
the equations can now be found by equating the numerical coefficients:
Solving for A, B, C, D:
so that the partial fractions are
