Question 2141
I have written other solutions for completing the square, see those. Salient points in the solution are:

{{{x^2 -8x + 16 = -2 + 16}}}
{{{(x-4)^2 = 14}}}

Use my past answers and your own skill to deduce the rest. Good luck

Also, I am not too sure what you mean by "lowest possible temrs" really, as the answer for x is the answer.
