x^2 + 12x = 5
x^2 + 12x + __ = 5 + __
x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).)
(x + 6)^2 = 41
x + 6 = (the square root of 41)
x = (the square root of 41) - 6.
Hope that helped :)

When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
Assuming A squared plus b squared equals c squared and a equals 10 and b equals 30 what is c?
C equals the square root of 1000 or 31.622776601683793319988935444327...
What is the diagonal of a 30-inch square box?
'A' squared plus 'B' squared equals 'C' squared. If 'A' and 'B' are the legs of the right angle comprising the sides of the box, 30 inches squared (900) plus 30 inches squared (900) equals 1800. The square root of 1800 is 42.426408711929.
