The work shows the first steps of writing a partial fraction decomposition.
(2x²+1)/((x-3)³) = (A)/(x-3)+(B)/((x-3)²)+(C)/((x-3)³)
2x²+1 = A(x-3)²+B(x-3)+C
2x²+1 = Ax²-6Ax+9A+Bx-3B+C
Which equations can be used in a system of equations to solve for the unknowns. Check all that apply.
a. A=2 -6
b. A+B=2
c. 3A-B+C=1
d. B=0
e. 9A-3B+C=1
