If I write: collect(1/s +(0.171/(s+7.854) -0.171/(s+1.146))) it will display: (s+6.45953750494)*(s+1.39339449506)/(s*(s+7.854)*(s+1.146)) How can I make it distribute the s? That is, put the expression in the form: like (b1*s^2 +b2*s +b3)/(a1*s^4+ a2*s^3 + a3*s^2 +a4*s +a5) If I write (s+1)*(s-1) I can't ever make it display (s^2 -1). Simplifying does not do what I expect. RE: CAS Multiplication - Didier Lachieze - 10-17-2018 05:01 AM Factor by degree: factor_xn() in CAS > Polynomial > Algebra should do what you need.
