Review the work showing the first few steps in writing a partial fraction decomposition. StartFraction 2 x squared + 15 x + 19 Over (x + 4) cubed EndFraction = StartFraction A Over x + 4 EndFraction + StartFraction B Over (x + 4) squared + StartFraction C Over (x + 4) cubed EndFraction

2x2 + 15x + 19 = A(x + 4)2 + B(x + 4) + C

2x2 + 15x + 19 = Ax2 + 8Ax + 16A + Bx + 4B + C

Which system of equations can be used to determine the values of A, B, and C?
