Answer:
s⁴-6s³+12s²-10s+3
Step-by-step explanation:
s³/(s²-2s+1) - 2/(s²-4s+3)
The denominators are (s²-2s+1) and (s²-4s+3). Since one is not a multiple of the other, the least common denominator will be their product.
(s²-2s+1)(s²-4s+3) = s⁴-4s³+3s²-2s³+8s²-6s+s²-4s+3
= s₄ +(-4s³-2s³)+(+3s²+8s²+s²)+(-6s-4s)+3
= s⁴-6s³+12s²-10s+3
Answer: 
<u>Step-by-step explanation:</u>
Factor both denominators to see which factors are missing from each denominator. Then multiply both fractions so they have the same LCD.
