In this question there is no symbol before 5xy.
(x + 1)(x - 4)
(x + 2)(x - 12)
(x+6)*(x-4)
The factors of that trinomial are (x - 13) and (x + 3) . Neither of them appears below.
(x + 10)(x + 4)
vbh
x + 4
. x + 4
(x+2)(x-9)
(x + 1)(x - 4)
(X-9)2
X - 4
(x+2)(x-3)
(x - 11)(x + 3)
x2+14x+40 = (x+4)(x+10) when factored
When factored it is: (x-9)(x+4)
(x - 10)(x - 3)
