see the attached figure
therefore
The solution of the system of equations is
Find the difference
The Greatest Common Factor (GCF) is the largest number that will be divided evenly into that number. For example, for 24, the GCF is 12. For a polynomial, the GCF is the largest polynomial<span> that will divide evenly into that polynomial.</span>
