Question

X^2-8x+16

Answer 1

what help do you need with that equation?

Answer 2

I'm guessing that you are trying to expand this equation? (can't remember the name, but have two equations that multiply together to form the one you have?

Answer 3

factoring?

Answer 4

If this is the case, then you need to begin by setting up a formula (x )*(x )
this way, you would have \[x^2\]
then you need to have two numbers that multiply together to get 16, that also add together to get -8

so, with trial and error, you should set up a table like this:
16= 1*16
16=-1*-16
16=2*8
16 =-2*-8
16= 4*4
16=-4*-4
which of these sets (when added together, e.g. 1+16) will give you the -8?

Answer 5

remember, your final answer should be able to multiply together to get the original answer.
(this is an example of how to multiply two sets, not the answer)
