Answer:

Step-by-step explanation:
Let's  find a particular solution. We need a function of the form  such that
 such that 
 and
 and 


then, 3a= 8, 2b+6a =0 and c+2b = 0. With the first equation we obtain 
a =  8/3 and replacing in the second equation 2b+6(8/3) = 2b + 16 = 0. Then, b = -8. Finally, c = -2(-8) = 16.
So, our particular solution is   .
.
Now, let's find the solution  of the homogeneus equation
 of the homogeneus equation  with the method of constants coefficients. Let
 with the method of constants coefficients. Let 


then 



 and
 and  .
.
So,  and the solution is
 and the solution is
 .

Using multiplication signal rules, it is found that:
A: Emma's statement is always false.
B: The result is always negative.
C: Emma's statement is always true.
The rule used for this exercise is as follows:
- When two numbers of different signals are multiplied, the result is negative.
- When two numbers have the same signal, the result is positive.
Part A:
- Three numbers are multiplied, all negative.
- The multiplication of the first two result in a positive number.
- Then, this positive number is multiplied by a negative number, and the result will be negative, which mean that Emma's statement is always false.
Two examples are:


Part B:
The rule is that the result is always negative.
Part C:
- The multiplication of the first two negative numbers result in a positive number.
- Then, this positive number is multiplied by another positive number, and the result will be positive, which mean that Emma's statement is always true.
Two examples are:
