Solve problem: P dollars is invested at annual interest rate r for 1 year. If the interest is compounded semi-annually, then the polynomial P(1+r/2)^2 represents the value of the investment after 1 year. Rewrite this expression without parentheses. â€œPâ€ is represented as the value of invested money â€œrâ€ is represented as the interest rate offered for this investment â€œAâ€ represents the amount of money that is due for this investment P(1+r/2)2 represents the value of the investment after 1 year or simply the â€œAâ€ We are required to rewrite the equation P(1+r/2)2 thus we get: A= P(1+r/2)2 = P(1+r/2)*( 1+r/2) * We show that the parenthesized equation is squared to remove the square = P(1+r2+r) *This is the result when we multiply 1+ r with 1+ r 4 2 2 =P+Pr+Pr2 *This is now the resulting equation as we have multiplied the â€œPâ€ to both 4 elements inside the parenthesis. Now, for the evaluation: Evaluate...
