Question

what is the value of the discriminant 3x^2-2x+5=0

Answer 1

For the equation
  ax² + bx + c = 0
the discriminant (d) is
  d = b²-4ac

Your equation has
  a = 3
  b = -2
  c = 5
Substituting these values into the expression for d, we get
  d = (-2)²-4(3)(5)
  d = 4 - 60
  d = -56

The value of the discriminant is -56.
