How Do You Find The Discriminant of a Quadratic Equation With No Solutions?

Find the discriminant of x2 - 4x + 5= 0

Summary

  1. You can find the discriminant inside the quadratic formula!
  2. A negative discriminant means we have no real solutions to this equation

Notes

    1. a is the coefficient in front of x2
    2. b is the coefficient in front of x
    3. c is the constant term
    1. The discriminant is equal to b2 - 4ac
    1. Our 'a' value is 1
    2. Our 'b' value is -4
    3. Our 'c' value is 5
    4. Plug these values into b2 - 4ac to get the value of the discriminant
