Step-by-step explanation:

f(x)=x^4+2x^2-1

Let x = -2

f(-2) = (-2)^4 +2(-2)^2 -1

       =16 +2*4-1

        =16+8-1

          24-1

Factor completely. Remember to look first for a common factor. If a polynomial is prime, state this.
Yakvenalex [24]
This one is prime.  The sum of two squares doesn't factor.

The more interesting case is q^2-1, which factors into (q-1)(q+1).

What is the 38th term of 459,450,441,..
galina1969 [7]

Answer:

The 38th term of 459,450,441,.. will be:

a_{13}=351

Step-by-step explanation:

Given the sequence

459,450,441,..

An arithmetic sequence has a constant difference 'd' and is defined by

a_n=a_1+\left(n-1\right)d

computing the differences of all the adjacent terms

450-459=-9,\:\quad \:441-450=-9

so

d=-9

The first element of the sequence is

a_1=459

so the nth term will be

a_n=-9\left(n-1\right)+459

a_n=-9n+468

Putting n=38 to find the 38th term

a_n=-9n+468

a_{13}=-9\left(13\right)+468

a_{13}=-117+468

a_{13}=351

Therefore, the 38th term of 459,450,441,.. will be:

a_{13}=351
