Question 317814: I don't believe I'm doing this one right and would like someone to walk through it with me to get the right answer.
Question:
(x-5)^2=11
Here's my work
5^2=25
6^2=36
36-25=11
Is that right or is there a different answer all together?

%28x-5%29%5E2=11 Start with the given equation.


x-5=%22%22%2B-sqrt%2811%29 Take the square root of both sides.


x-5=sqrt%2811%29 or x-5=-sqrt%2811%29 Break up the "plus/minus" to form two equations.


x-5=sqrt%2811%29 or x-5=-sqrt%2811%29 Simplify the square root.


x=5%2Bsqrt%2811%29 or x=5-sqrt%2811%29 Add 5 to both sides.


--------------------------------------


Answer:


So the solutions are x=5%2Bsqrt%2811%29 or x=5-sqrt%2811%29.
