Solve 2x2 + 8 = 0 by graphing the related function. There are no real number solutions.
There are two solutions: V8.
There is one solution: 2
There are two solutions: 2 and -2.

there are no real number solutions

Step-by-step explanation:

2x² + 8 = 0

x² + 4 = 0

x² = -4

these solutions all involve "i", the imaginary or complex numbers, as normally the square of any number has to be positive (and cannot be negative).

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
