Answer:
832
Step-by-step explanation:
If you have one group of 832, and put it into 1 group you get 832
Exception if the integer is a negative
P3(4) = p12 them p12 * p8 = P160 (false)
Completing the square follows the principle of taking

and converting it into

where d is the 'correctional number' as I like to call it - i.e. the number that converts the expanded bracket into the +c, since the expanded bracket will give us

.
In this case, 2/2=1 so we have the first part:

.
Expanding this gives us

. We need c to be 9, so we can just add 8.
Putting this together:

Now we can solve it more easily.
