<span>Part A: First, we factor out a^2 to obtain: a^2 [5x^2 - 19x - 4] = a^2[(5x+1)(x-4)]
Part B: By inspection, we can use the factors (x+7)(x+7). To check that we have indeed chosen correctly, we will multiply our factors to obtain x^2 + 7x + 7x + 49 =
x^2 + 14x + 49 = 0, which is correct.
Part C: Again, we can use trial and error and try the factors (x+10)(x-10). Multiplying throughout, we obtain x^2 + 10x - 10x - 100 = x^2 -100.</span>
I believe the correct answer is D, competition among manufacturers in the marketplace is prohibited. Capitalism encourages competition.
I t is very difficult to find out a nation´s feeling towards a conflict which had many consequences, specially because this is a sensitive topic. The dicussion nowadays is focused on how can be interpreted the German role during WWI. And the discussion is around two specific concepts: guilt or responsibility.
