What is the value of the discriminant, b2 - 4ac, for the quadratic equation 0 = x2 - 4x + 5, and what does it mean about the number of real solutions the equation has?

The discriminant is - 4, so the equation has 2 real solutions.

The discriminant is - 4, so the equation has no real solutions.

The discriminant is 35, so the equation has 2 real solutions.

The discriminant is 35, so the equation has no real solutions.

Nia Reid · Answer 1

The value of the discriminant in this equation is (-4) ^2-4*1*5 which is - 4

Just for reference;

If the value of the discriminant is negative, the equation has no real solution

If the value of the discriminant is positive, the equation has two real solutions

If the value of the discriminant is zero, the equation has one real solution.

Therefore, the discriminant is - 4, so the equation has no real solutions
