The work shows the first steps for writing a partial fraction which equations can be used in a system of equations
decomposition
to solve for the unknowns. Check all that apply.
4x3-5 AX + B CX + D
(2x2 + 1)2 (2x2 + 1)(2x2 + 1)2
O A=0
4x3 - 5 = (AX + B)(2x2 + 1) + (x+D
OB=0
4x3-5 = 2 AX3+ Ax + 28x2 + B + Cx +D
OD=-5
O A+C=0
2A + 2B = 4
Done
