First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
The answer I'm pretty sure is B but I can't really explain it, sorry
2x(x+4)-1(x+4)
2x^2+8x-x-4
2x^2+7x-4
Answer:
Required solution is
where A and B are constants.
Step-by-step explanation:
Given nonhomogenous differential equation is,
with 
To find another solution, consider
be such that,

Hence,
where A and B are constants.
Let



Hence,
where A and B are constants.
which is required solution.
Answer:
The 10th term is -524,288
Step-by-step explanation:
The general format of a geometric sequence is:

In which r is the common ratio and
is the previous term.
We can also use the following equation:

In which
is the first term.
The common ratio of a geometric sequence is the division of the term
by the term 
In this question:

10th term:

The 10th term is -524,288
