will be 
<h3>What will be the factors of the given equation?</h3>
It is given that

Now by simplifying it

Now from the formula, we know

So it will become

Thus the factors of the given expression
will be (7x+12)(7x-12)

You want to isolate C, so the first step would to have it be positive. You would do this by adding C to both sides of the equation to cancel the C on one of the sides out like this:

. Then you want to cancel out the P, so you subtract it on both sides like this:

And that is your answer
Perimeter of a rectangle = 2(l+w)
Length = 4-7(3x+4y)
=4-21x-28y
Width = 3x(-2y)
=-6xy
Perimeter
=2(4-21x-28y-6xy)
Answer = 8-42x-56y-12xy
