Jared’s stock portfolio grows according to the formula a=2x^2-31x+25, where a is the amount in the portfolio, in thousands, and x is the amount of time the money has been in the portfolio, in months. When will Jared’s portfolio be at a value of 10,000 dollars?

10 = a      ( 10 thousand)

 

10 = 2x^2 - 31x + 25

   0 = 2x^2 -31x + 15     use Quadratic Formula t find x = 15   or  1/2     months
