Question

if s^2(a+b)+s(b+c)+a+c=1

then hw is a+b=0,c+b=0, a+c=1

Answer 1

@myininaya help me

Answer 2

this is partial fractions?

Answer 3

well in any event, you are trying to set the coefficients on each side equal
on the right, the coefficient of the s^2 term must be zero, since there is no s^2 term
hence the coefficient for s^2 on the left must also be zero

Answer 4

similarly with the s term
the only term that is on the right is the constant term, which is 1
hence the constant term on the left (the term that does not have an s in it) must equal 1
a+c=1
