The equation is
2 {x}^{2}  - 3x + 5 = 0
Here
a = 2
b = -3
c = 5

Now D =
 =  {b}^{2}  - 4ac \\  = ( - 3) {}^{2}  - 4 \times 2 \times 5 \\  = 9 - 40 \\  =  - 31
As D is a negative Number so the roots of the equation is unreal and imaginary.

Here is your answer

b {}^{2}  - 4ac \\  =(  - 3) {}^{2}  - 4 \times 2 \times 5 \\  = 9 - 40 \\  =  - 31
So The Roots are non real complex

Hope it helps
