consider the following pair of mortgage loan options for a $115,000
[1-(104)
mortgage. which mortgage loan has the larger total cost (closing costs + the amount paid for points + total cost of interest)? by how much?
mortgage a: 20-year fixed at 12.25% with closing costs of $1500 and 1 point.
mortgage b: 20-year fixed at 11.25% with closing costs of $1500 and 2 points.

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.

-5, your answer was correct
