You can put this solution on YOUR website!
Whenever you are given a quadratic equation in which you cannot factor, we can solve it using the quadratic formula
(Note the quadratic formula states that if I have a quadratic in the form
ax%5E2%2Bbx%2Bc=0
then
x=%28-b+%2B-+sqrt%28b%5E2-4ac%29%29%2F2a



So in our case our a=8 our b=3 and our c=-4. From here it is just substituting these three values into the equation above and using your calculator**make sure you put brackets in the correct positions when using the calculator or else it may calculate a different value**)

Hopefully this helps a bit, let me know if you are still unsure.
