Answer:
Step-by-step explanation:
we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference
we have
Let
we have that
so
The common difference is equal to 9
We can write an Arithmetic Sequence as a rule:
where
a_n is the nth term
a_1 is the first term
d is the common difference
n is the number of terms
Find the 38th term of the arithmetic sequence
we have
substitute the values
Answer:
Step-by-step explanation:
Take out the common factor from the first and second terms and again from the 3rd and fourth terms.
x^2(x + 2) - 9(x + 2)
Take out x + 2 from around the minus sign.
(x + 2)(x^2 - 9)
Factor x^2 - 9 which will come out to the difference of squares.
(x + 2)(x + 3)(x - 3)
This is how it factors.
You could also use synthetic division if you know how it works.
-2 || 1 2 -9 -18
-2 0 18
====================
1 0 -9 0
This gives you (x + 2)(x^3 - 9) just as before.
