which method do you use to solve this equation.(x1)^2=7.
Is it the factoring method or the sqare root method
I would take the square root of each side.
(x1)= + sqrt7
Now for the factoring method:
(x1)^2=7
(x1)^27=0
you have a difference of two squares..
((x1) +sqrt7)((x 1) sqrt7)=0
so either term can equal zero. Same answer as above.
Is the answer considered x=1+ or  square root 7 or just root7
