If you mean 2x^2 -3x +8 = 0 then the discriminant works out as
-55 which is less than 0 meaning that the equation has no real
roots and so therefore no solutions are possible.
Q: What is the value of the discriminant b2 and minus 4ac for the quadratic equation 0 and minus2x2 and minus 3x plus 8 and what does it mean about the number of real solutions the equation has?
