What is the value of the discriminant for the quadratic equation 0 equals X squared minus 4X +5 and how many number of real solutions does the equation have

Discriminant: -4

No real solutions

Step-by-step explanation:

You might remember this long, seemingly very hairy thing called the quadratic formula from earlier in algebra:

The discriminant of a quadratic equation of the form is that bit under the square root: . What does the discriminant tell us? Since we're taking its square root, we know that is only real for non-negative values of . If , we have two real roots, one for and one for . If , the function has a rational root, since the formula becomes

In your case, we have the equation ; here, , , and , so our discriminant is . Since we'd have a negative under our square root in the quadratic formula, we have no real solutions.
