#### Answer

The answer is below.

#### Work Step by Step

You can pick any problems you want in order to do this. Here is an example using problem 2 in problem set 10.3.
We are told that $x_1 + x_2 = -\frac{b}{a}$. Using b = 3 and a= 1, we find:
$-4 +1 = -3/1 \\ -3 = -3$
We are also told that $(x_1)(x_2) = ca$ Thus, using c = -6 and a = 1, we find:
$ (-1)(6) = (-6)(1) \\ -6 = -6$
Since these are both true, we see that we got the correct solution.
