Yes,
x^2 -4x+4
= x^2 -2x-2x +4
= x (x-2) -2 (x-2)
= (x-2)(x-2)
As you can see it has repeated factor.

Answer:
4
Step-by-step explanation:
Written in standard form, the quadratic is ...
x^2 -2x -3 = 0
This can be factored as ...
(x -3)(x +1) = 0
so the solutions are ...
x = 3, x = -1 . . . . . . values of x that make the factors zero
The difference of interest is ...
3 -(-1) = 4
the profit is a polynomial function :
p(x) = x^4 − x^3 − 24
the average profit per unit of product sold is :
ap(x) = (x^4 − x^3 − 24)/(x+2)
now,
(-2) is an "obvious" zero of p(x)
therefore : p(x) is dividable by (x+2)
and
the long division of p(x) by (x+2) gives :
Answer:
ap(x) = x^3 - 3x^2 + 6x - 12
