Solve x^2-4=5 by graphing the related function.
1)there are two solutions 1 and -1
2)there is one solution 1
3)there are no real number solutions.
4)there are two solutions 3 and -3

I think the correct answer from the choices listed above is option 4. The solution of the equation given as  x^2-4=5 would be 3 and -3. We calculate as follows:

 x^2-4=5
 x^2 = 5 + 4 = 9
x = √9
x1 = 3
x2 = -3

Hope this answers the question. Have a nice day. Feel free to ask more questions.
