X^2 + 1 = 0
find the solution
The Attempt at a Solution
As simple as this:
what is the solution to x^2 +1 = 0
.... my question, why am I wrong in thinking x^2 = -1 as a possible solution?
(-1/2)² = 1/4, so that's not a solution to X² + 1 =0Oh I see.... Well, a solution to x^2 could be [tex]\pm 1[/tex]. So what is the solution, I am a bit confused. Would it be
x = -1/2
No, it's not. You have already said that x^2= -1, not [itex]\pm 1[/itex]. Now you need to get x itself, not x^2. You need to "undo" the square- what's the opposite of squaring?Oh I see.... Well, a solution to x^2 could be [tex]\pm 1[/tex].
You seem to be confused about what "solution to an equation" means. What level mathematics are you taking? Where did you get this problem? Have you studied complex numbers.So what is the solution, I am a bit confused. Would it be
x = -1/2
