Question

what is the value of the discriminant for the quadratic equation 0 = 2x2 x – 3? discriminant = b2 – 4ac

Answer 1

Discriminant of 2x²+x-3=0 is:

25

Explanation:

the discriminant of the equation ax²+bx+c=0 is:

discriminant=b²-4ac

Here, we are given a quadratic equation 2x²+x-3=0

⇒ a=2, b=1 and c= -3

discriminant=1²-4×2×(-3)

= 1+24

=25

Hence, Discriminant of 2x²+x-3=0 is:

25

Answer 2

discriminant = b^2 - 4ac; where a = 2, b = 1 and c = -3
d = 1^2 - 4(2)(-3)
d = 1 + 24
d = 25
