For the Partial Fraction , Parts (Denominator - Repeated Linear Factor ) , how to prove the biggest power of x^3 in the denominator ?
For example
P(x)+Q/(x-3)^3 , how to prove to A/x-3 + B/(x-3)^2 + C/(x-3)^3

shamil98 · Answer

P(x)+Q/(x-3)^3  = A/x-3 + B/(x-3)^2 + C/(x-3)^3
?

shamil98 · Answer

are you given any more information?

anonymous · Answer

nope just wanna show that P(x)+Q/(x-3)^3  = A/x-3 + B/(x-3)^2 + C/(x-3)^3

shamil98 · Answer

x >= 4 so we don't get undefined through division i guess.
so if x = 4
P(4) + Q = A + B + C
