Question 260026
Hello, 
The whole key to algebra equations is get the variable "x" all alone. So when we have an equation like this: x^2=40 
The only way to get it to be "x" is square root both sides. When we sq rt x^2 it just becomes "x". But we need to sq rt the other side too so to keep it balanced.
(sq rt)x^2=(sq rt)40
x=6.3246 Rounded off (Also a minus 6.32)
Now we can check this to see if it's right by putting the answer back into the original equation.
