MATLAB: How can I use partfrac command

Question

Hi

i want to find the partial fraction expansion for the function

f(x) = (8x^2+37x+32)/((x+1)(x+2)(x+4))

I want to find it using partfrac command

when I try partfrac((8*(x^2) + 37*x + 32) / ((x + 1) * (x+2) * (x+4)))

I get an error: Undefined function or variable 'x'.

How can I do it?
