The domain for N is All integers where n ≥ 1

<u>Solution:</u>

According to statement a1 = 2 and r = 4. This shows that r is greater than 1.

If r is greater than 1 than it includes integers greater than 1 or equal to 1. It does not include all the real numbers because real numbers include negative numbers also.

If starting value is 2, if we put n=0, then we get 2, but if we put a negative value than we would get a number which is not a part of our sequence.

Thus the domain of n is All integers where n greater than or equal to 1

Answer:

2 (x + 2) (x - 1)

Step-by-step explanation:

Simplify the following:

2 x^2 + 2 x - 4

Factor 2 out of 2 x^2 + 2 x - 4:

2 (x^2 + x - 2)

The factors of -2 that sum to 1 are 2 and -1. So, x^2 + x - 2 = (x + 2) (x - 1):

Answer: 2 (x + 2) (x - 1)

Answer:

Factoring the term $3x^2-75$ we get $\mathbf{3(x+5)(x-5)}$

Step-by-step explanation:

We need to solve the polynomial: $3x^2-75$

First we see that 3 is common term, so taking 3 as common

$3(x^2-25)$

We know that 25 = 5x5 = 5²

So, replacing 25 with 5²

$3(x^2-5^2)$

We know that, $a^2-b^2=(a-b)(a+b)$

Applying this in our equation: $x^2-5^2=(x+5)(x-5)$

$3(x+5)(x-5)$

So, factoring the term $3x^2-75$ we get $\mathbf{3(x+5)(x-5)}$
