$\implies2 {x}^{2} - 3x + 5 = 0\\ \implies As\:we\:know\:that$

$\huge\boxed{\fcolorbox{white}{yellow}{Discrimnant}}$ = $\implies{b}^{2} - 4ac$

$\implies on \: comparison \: we \: get \: \\ a = 2 \\ b = - 3 \\ c = 5$

on putting the value we get ,

D =

$\: \: \: \: \: \: \: \: \: {b}^{2} - 4ac \\ \: \: \: \: \: = { - 3}^{2} - 4 \times 2 \times 5 \\ \: \: \: \: \: = 9 - 40\\ \: \: \: \: \: = - 31$
