How do you find the zeros of # y = -1/5x^2 - 7/3x + 2/3 # using the quadratic formula?
The first thing to do is to simplify the equation replacing the reaction by the equivalent fraction with the same denominator:
Now multiply both side by 15:
now apply the second-degree formula:
Theres is now way to simplifiy sqrt(1345) so the solution may stay lique this.
In the case of the need of a number the solution are:
0.27904 and -11.9457
