Question

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

Answer 1

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

Answer 2

yaya

Answer 3

are you given any more information?

Answer 4

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

Answer 5

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

Answer 6

u wait i am going to scan somethg
