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 = 2x^2 -31x + 25            (10 is  10 000 in thousands)

2x^2 -31x +15 = 0    Quadratic formula shows x = 15 months       ( 1/2 month also shows as a possible....but unlikely)
