What is the value of the discriminant, b^2 − 4ac, for the quadratic equation 0 = x^2 − 4x + 5, and what does it mean about the number of real solutions the equation has?

Answers

Answer 1

Answer: b^2 - 4ac in this quadratic equation would be 16 - 20, or -4. A negative discriminant means there is no real answer to the equation.

Answer 2

Answer:

Answer: I believe it’s B but when I solved it normally I got -36 but I guess it just dident work right because when I took away the negative it worked

Answers

We see that n is in the set of natural numbers (1,2,3,4,5,...), so of course m should be in the natural numbers. However, we see that 2n^2, when square rooted, is $n√(2)$ . With n in the natural numbers, the square root of m, or o, can never be a natural number but is always an irrational number. Therefore, this equation has no solutions.
