<span>B.
First look to simplify:
(40x^2 + 22x - 6) = (2)(20x^2 + 11x - 3)
now factor knowing one side must be (4x + 3)
(2)(20x^2 + 11x - 3) =
(2)(4x + 3)("SomethingX" + "something")
4x times SomethingX must = 20x^2
Something must be 5 (4x * 5x = 20x^2)
now we know:
(2)(20x^2 + 11x - 3) =
(2)(4x + 3)(5X + "something")
3 times "something" must equal -3
that must be -1... therefore:
(2)(20x^2 + 11x - 3) =
(2)(4x + 3)(5X + -3)
The fact that this works and the others don't means the answer is B.</span>
