which method do you use to solve this equation.(x-1)^2=7.
Is it the factoring method or the sqare root method
I would take the square root of each side.
(x-1)= +- sqrt7
Now for the factoring method:
you have a difference of two squares..
((x-1) +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
