Use the
Binomial expansion theorem to find and simplify each
term.
Man that was a lot to type out, hopefully i helped, and Gosh I hope I get a brainly for all that freaking typing. hehe~ ^.^
Answer:
5) A = 4
6) B = -1
Step-by-step explanation:
Question 5
Substitute (2, -5) into the equation to find the missing coefficient
A(2) + (-5) = 3
2A - 5 = 3
2A = 8
A = 4
Question 6
Substitute (2, 7) into the equation to find the missing coefficient
3(2) + B(7) = -1
6 + 7B = -1
7B = -7
B = -1
4n/4n-4 × n-1/n+1
= 4n(n-1)/(4n-4)(n+1)
= (4n^2 - 4n)/(4n^2 + 4n - 4n-4)
= (4n^2 - 4n)/(4n^2 - 4)
= 4(n^2 - n)/4(n^2 - 1)
=(n^2 - n)/(n^2 - 1)
