a = 8, b = 2, and c = -3.
The sum of the roots is equal to -b%2Fa+=+-2%2F8+=+highlight%28-1%2F4%29.

You can solve this straight from the basic formulas and then plug in the corresponding values from your given quadratic equation.
From the general ax^2+bx+c=0, you have learned that the solutions are %28-b+%2B-+sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282a%29. Sum those two:
, simplify that.
s=%28-b+%2B+%28-b%29%29%2F%282%2Aa%29
s=-%282b%2F2a%29
highlight%28s=-%28b%2Fa%29%29

Now, refer to what in your given corresponds to a and to b;
8x^2+2x-3=0
s=-%28b%2Fa%29
s=-%282%2F8%29
highlight%28s=-%281%2F4%29%29
