Compounded semiannually. P dollars is invested at annual

interest rate r for 1 year. If the interest is compounded

semiannually, then the polynomial P(1+r/2)^2represents the

value of the investment after 1 year. Rewrite this expression

without parentheses. Evaluate the polynomial if

P =$200 and r =10%.

it is totally impractival to write P(1+r/n)^n without brackets, unless n=2

that would be P(1 + r + r^2/4)

= P + Pr + Pr^2/4

amount = 200(1.05)^2

= 220.50

notice in the expanded version

amount = 200 + 200(.10) + 200(.10)^2/4

= 200 + 20 + 0.5

= 220.50

mmmh, compare the two calculations.
