Question

what os the answer of this?​

Answer 1

Step-by-step explanation:

GIVEN :-

$\sf \: 2 {x}^{2} - 3x + 5 = 0$

TO FIND :-

$\sf \: Discriminant \: of \: the \: equation$

SOLUTION :-

$\sf \: If \: a \: quadratic \: equation \: is \\ \sf \: \: a {x}^{2} + bx + c \: \: then$

$\sf \: Formula \: of \: Discriminant \\ \sf \: D= {b}^{2} - 4ac$

$\sf \: here \: \: \: a = 2 \: \: \: \: \: b \: = - 3 \: \: \: \: \: \: c = 5$

$\sf \: then \: \: Discriminant \\ \sf ( D)= {b}^{2} - 4ac \\ \sf= ( - 3) {}^{2} - 4(2)(5) \\ = 9 - 40 \\ \sf = - 31$

$\green{ \boxed{ \sf \: Discriminant \sf \: D= - 31}}$
