x = sqrt2+5 = 6.414

x= -sqrt2 +5 = 3.586

Explanation:

Usually we would multiply out the bracket and make the whole equation equal to 0.

However, this is a special case because there is no x-term, so we can leave it as it is and just find the square root of both sides.

(x-5)^2 = 2

x-5 = +-sqrt2

x = sqrt2+5 = 6.414

x= -sqrt2 +5 = 3.586
