If you multiply (x - k)(x + k), you get $x^{2} + k*x - k*x - k^{2}$ which is equal to $x^{2} -k^{2}$ . Now you can see that $\frac{1}{3} *x^{2} - 2$ must be equal to $\frac{1}{3}*(x^{2} - k^{2})$ which is equal to $\frac{1}{3}*x^{2} - \frac{1}{3}*k^{2}$ . Now we just need to solve $2 = \frac{1}{3}*k^{2}$ . The final answer is $k = +- \sqrt{6}$ .

A current trend is for employers to require _______ and ______ to establish job eligibility.

snow_tiger [21]

Answer:

b) job experiences; degrees

Explanation:

In recent times, the employers tend to require job experience and degrees from the people that apply for jobs. The reason for this is that the economy is extremely competitive, so the employers try to get people that are already qualified for the job, will not need training for it, and that can contribute directly. While this is good for the companies and their economic interests, it is actually very bad for the young people that try to find job, as they are required to have experience, but rarely who employs them so that they can gain that experience, sot he percentage of unemployed young people is on the rise unfortunately.
