2x^4 + x^3 − 8x^2 − 4x
= x ∙ (2x^3 + x^2 − 8x − 4)
= x ∙ (x^2 ∙ (2x + 1) − 4 ∙ (2x + 1))
= x ∙ (x^2 − 4) ∙ (2x + 1)
= x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1)
Thus the roots are:
x ∙ (x − 2) ∙ (x + 2) ∙ (2x + 1) = 0
⇒ [x = 0] or [x − 2 = 0] or [x + 2 = 0] or [2x + 1 = 0]
⇒ [x = 0] or [x = 2] or [x = −2] or [x = − 1/2]
Sin x = a/c
cos x b/c
tan x = a/b

NAFTA as an organization is very important for the three North American economies, the USA, Canada, and Mexico. It is basically a regional trade organization which has lifted the borders when it comes to trade, thus enabling free movement of goods between these three nations. This has resulted in rise of the economies of all three nations, as there were no trade barriers between them anymore. The companies where able to move their facilities and to operate in each of these countries, which brought them larger profits. The Canadian and the US economies became almost like one, as the companies managed to operate in both places, and to become major players in the market, this especially goes for the US companies that made Canada their home terrain.
