xy(x - 2y)(x + 2y)
There is one way to determine weather each binomial is a factor of X-4. The division of polynomials is what determines each binomial.
(x - 3)(x - 9)
(x + 1)(x + 5)
(x - 2)(x - 4)
(x - 4)(x - 1)
(x - 6)(x - 7)
(x - 9)(x - 4)
x2-7x-44 = (x+4)(x-11) when factored
The expression does not have any real binomial factors. x is a monomial factor, and the other two involve complex numbers.
x2-64 = (x-8)(x+8) when factored
The factors are (x + 6) and (x - 3)
(x - 14)(x - 2)
