In a quadratic equation of the form (ax^2 + bx + c), the discriminant is equal to (b^2 - 4ac).
So for the first question it would be
4^2 - 4*(6*-2) = 64
Second question (-7)^2 - 4*(9*5) = -131
You can do the rest.
For this case we must solve the following linear equation:
Adding to both sides of the equation we have:
Subtracting 17 from both sides of the equation:
Different signs are subtracted and the major sign is placed:
We divide by 14 on both sides of the equation:

Answer: The source has the potential to create bias because it was sponsored by companies that will benefit from it. This might have been avoided by stoping these companies from sponsoring the study.
Explanation:
A study is biased if its results or process is not objective, which means they have been influenced by a specific perspective or interest, and the results are inaccurate. One of the factors that causes bias is the participation of entities with economic interests in the study.
This occurs in the case described because a candy and a chocolate company sponsored the studies, and therefore results might be modified to benefit the companies. According to this, the study has the potential of being biased, and the main source is the fact it was sponsored by companies with interests.
Besides this, this can be avoided if the study does not accept sponsoring by companies with specific interests. In this way, the study will be objective, and the results will not be influenced, which means the information provided by the study would be accurate and credible.
