here`s a graphic, if it helps...
(the area will be the part past x=2..where both curves intersect.
(they`ve just factored f_2, equated them, and divided by (4-x)

Hi I'm puzzled on a question could anyone help?
The area formed by two functions:
F1(x)=1/x-2 f2=4x-x^2
question?
show that the intersection points between the two curves f1(x) and f2(x) are solutions to the equation;
X=1/(x-2)(4-x)

X=1/(x-2)(4-x)
The curves intersect when the functions are equal
Set them equal and do a bit of rearrangement
