1. Step-by-step explanation:

   2x²-3x+5=0

   a=2 b= -3 c=5

   D=b²-4ac

   D=(-3)²-4×2×5

   D= 9-40

   D= -31

   D<0

2. Answer:

   Discriminant ( D ) = b² – 4ac.

   2x²-3x+5= 0

   Here,

   a= 2

   b= -3

   C= 5

   then

   (D)= (-3) ²-4×2×5

   => 9-40

   => -31

   so discriminant of equation 2x²-3x+5= 0 is -31
