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)^2
represents the
value of the investment after 1 year. Rewrite this expression
without parentheses. Evaluate the polynomial if
P = \$200 and r = 10%.

• basic Algebra -

Value = P + Pr + Pr^2/4
Plug in the numbers.
