Re: rearranging an equation

Solution :- Given y(S^4 + 3S^2 -12) = (104/s)+3 -24 +12S^3 - 3S^2 + 25S -15

s(S^4+3S^2-12)Y=104+s(12S^3-3S^2+25S-36)

because s(S^4+35^2-12)?0

Y=(12sS^3-3sS^2+25sS-36s+104)/s(S^4+3S^2-12)

Re: rearranging an equation

Please clarify the right hand side of yuor equation. What you wrote is this:

But I suspect what you meant is this:

Why didn't you combine the -24 and -15 terms?

One option is to multiply both sides through by (S+3), then divide both sides by the Y coeffeicient:
