We have been given an equation 0 = x^2-4x + 5. We are asked to find the discriminant of our given equation.    

We will use discriminant formula to solve our given problem.

D=b^2-4ac, where,

D = Discriminant,

b = Coefficient of x term,

a = Coefficient of x^2 term,

c = Constant.

D=(-4)^2-4(1)(5)

D=16-20

D=-4

When D is less than 0, then equation has no real solutions.

When D is equal to 0, then equation one real solution.

When D is greater than 0, then equation has two real solutions.

Since -4 is less than 0, therefore, our given equation has no real solutions.

Compare and contrast area and volume
levacccp [35]
Both area and volume, in a vague way, can be seen as the measurement of the size of something.  They are different because area is the size of a two-dimensional shape (like a square or a triangle), and volume is the size of a three-dimensional shape (like a cube or a pyramid).
