Hi Again Theresa;
x^{2}8x48/x+4
Let's factor...
x^{2}8x48
For the simplification process, one parenthetical equation must =(x+4)
For the LAST of FOIL, 4 x 12=48
For the INNER and OUTER of FOIL, 4x12x=8x
So...
(x12)(x+4)
Let's simplify...
[(x12)(x+4)]/(x+4)
Let's cancel where appropriate...
[(x12)(x+4)]/(x+4)=x12
