Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.
For us, it looks like this:
which simplifies to
Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that
so we will do a rewrite on that equation above:
which simplifies further to
This is the answer but we can separate it into its proper standard form which is
and
This means that we have to didvide the 12 inches wide side into 3 parts: one of 3.5 inches, and two other, of equal size (the margins).
the margins together will have (12-3.5=8,5) inches, which means that each of them will hace half of this: so we have to divide 8.5 into 2.
this is: :
8.5/2=4.25
so he has to to put it 4.25 inches from each side.
