Find the sum of the solutions of this equation 20x^2-39x-80=0

This is 'nice':

The sum of the solutions is the coefficient with 'x', change it sign and divide by the coefficient of x^2:

sum = 39/40.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
