x^2 - 8x + 16 = 0
(x )(x )
You need two numbers that when multiplied are equal to 16, and when added are equal to 8.
These two numbers are 4 and 4 (4 * 4 = 16, 4 + 4 = 16)
Then you need to figure out if these are positive or negative. Since 16 is positive, you know that the numbers are either both positive or both negative. Since the 8 is negative, you know they must be negative.

Why do the factors of 16 are also factors of 32 and 64?
All numbers have factors. Some numbers have some of the same factors as other numbers. Multiples of numbers have all of the factors of numbers that are factors of them, plus some of their own. 32 is a multiple of 16 and will have all of its factors. 64 is a multiple of both 32 and 16 and will have all of their factors.

WHAT IS 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16 plus 16?
The answer is 192. Simply add up all of the numbers arithmetically like you would for two plus two. To make sure the answer is correct, check your work using a calculator.
How do you factor x cubed plus 4x squared plus 16x plus 64?
x3 + 4x2 + 16x + 64 =x2*(x + 4) + 16(x + 4) = (x + 4)*(x2 + 16) which has no further real factors.
