Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.
A=p (1+r/k)^kn
A future value
P present value 6000
R interest rate 0.08
K compounded semiannual 2
N time 35years
A=6,000×(1+0.08÷2)^(2×35)
A=93,429.71
