X2 - 5X = 24
X2 - 5X - 24 = 0
(X - 8)(X + 3)
X = 8
----------------and
X = - 3

It's a second degree equation in 'x' that has no real solution. No real number in the place of 'x' can make that equation a true statement. There are only two "imaginary" numbers that 'x' can be: + 4i sqrt(5) - 4i sqrt(5)

The result is all real numbers.
The answer is 8.5, which is one solution and real.
all real numbers
All real numbers that are greater than or equal to zero
y is greater than 0 x exist in a set of real numbers
The two rational solutions are (0,0,0) and (1,1,1). There are no other real solutions.

The equation does not have a real number solution. Using the quadratic formula will give it's conjugate pair complex solution.
x2 = -25 There exists no real number for which this is true, so we must use imaginary numbers... x = 5i
106
Yes, Any real number squared is a real number. In this case that number is 25.
There are infinitely many such numbers. One such is 181.81828384881882883884...
The result is all real numbers.
