No, it requires the use of the binomial theorem, (x + 4)2 (proven by Pascal's Triangle and other polynomial formulas), where (x + a)2 = x2 + 2ax + a2. Thus, we have:
x2 + 2(4)x + 42 = x2 + 8x + 16

Yes because its discriminant is equal to zero
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.
