CAS Multiplication - rushfan - 10-17-2018 01:54 AM
I have the following cas expression:
1/s +(0.171/(s+7.854) -0.171/(s+1.146))
How can put the expression under a common simplified denominator?
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.

Factor by degree: factor_xn() in CAS > Polynomial > Algebra should do what you need.

Try normal.
