Answer:
8) -8, -9
9) 4, 
Step-by-step explanation:
8) x² + 12x + 27
Solutions of a polynomial means the values of 
such that the polynomial becomes zero. 
.
We use the following formula to determine the solutions of a quadratic equation of the form: 
In this equation, 
Substituting in the formula, we have:
Taking 2 common outside we get:
Therefore, we get two solutions viz, x = -3, -9.
9) 2x² - 9x + 4 = y
X- intercepts of a polynomial means the value of x such that y = 0. It means the roots of the polynomial.
Solving the equation using the formula above, we get:
The values of x = 4, .
Hence, the answer.
In a randomized block design, it is expected treatments are randomly assigned within each block.
<h3>What does a randomized block design imply?</h3>
- Subjects are divided into blocks based on a specific features such as age, gender, education, etc.
- Within each block subjects that receive treatment and does who do not are randomly assigned.
- The treatment in all blocks is the same. For example, if the purpose is to study the effect of medicine all treatment subjects should receive the same medicine and dose.
<h3>What is the purpose of this design?</h3>
The purpose is to minimize the effect of certain factors such as age.
Based on the above, it is expected in this experiment the treatment is randomly assigned to a specific number of subjects within each block.
