Finacial PolynomialsRoshonda YoungMAT221: Introduction to AlgebraInstructor: Pamela JosifekOctober 20, 2013Financial PolynomialsOn page 304, problem 90 says that P dollars is invested at annually interest rate r for 1 year. If the interest rate is compounded semiannually then the polynomial is P(1{+r/2)^2, which represents the value invested after 1 year. When starting this problem the first thing I need to do is rewrite the polynomial expression without parenthesis, so I will need to use FOIL for the binomial (1+r/2)^2.P(q1+r/2)^2 is the original expression, then the squared Amount multiplies itself P(1+r/2) (1+r/2), now I used the FOIL for the expression P(1+1r/2+1r/2+r/2^2, then I combined the like terms next the p is distributed across the trinomial P(1+2Pr/2+Pr/2^2. This would be a traditional polynomial that is in ascending order, because the highest exponent is in the last term instead of the first term. It would not be in descending order because the highest exponent is not the first term. Now I will complete the polynomial using the numbers that I was given for variables P and r.P=200 and r=10% (.10), 10 percent is turned into a decimalP+2Pr/2+Pr/2^2, T
