The value of x is equal to -5/6
To solve this question, we have to add two polynomials together. The polynomials are;
<h3>Addition of Polynomials</h3>
This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.
In this given question, let's add the polynomials together.

Now, let's equate this with the last polynomial given

Let's solve for x

This question doesn’t really make sense- is it multiple choice, if so what are the options? A can be anything as long as it’s the same?
Answer:
The answer is 75 tests for 150 people.
Step-by-step explanation:
Firstly, with 150 people, we can divide into 15 groups; and the probability of disease is 0.04, there are 6 persons who possibly get disease.
Therefor, the maximum number of groups with an individual getting disease is 6. Then, 6 * 11 tests = 66 tests required.
15 groups - 6 groups with disease = 9 groups of negative with 9 tests.
In conclusion, there are 75 tests required.
