Question

3. Find the discriminant of the quadratic equation 2 x2 - 3 x +5=0
​

Answer 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

No real roots exit

Answer 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
