Looking at the expression, we see that the only common factor shared between these three terms is x.
We factor out x:
x(2x2 + 4x - 1)
We can no longer find any common factors, so this is the final answer.
Umm I think you divide a from b maybe
Answer:

The general solution is

Step-by-step explanation:
Given differential equation is
y''-4y'+4y=0
and 
To find the
we are applying the following formula,

The general form of equation is
y''+P(x)y'+Q(x)y=0
Comparing the general form of the differential equation to the given differential equation,
So, P(x)= - 4







The general solution is

Answer: x - 2 + 5 = x - 12
Step-by-step explanation:
At first I was confused. Then I read the question again and translated it.
Less than translated means - 2.
A number, aka X.
and means plus(+).
when you put that together you get,
x - 2 + 5.
The next step is to translate to second part of the equation.
Is means equals(=).
So far we have: X - 2 + 5 = 12.
<em>This is where I got confused...</em>
After solving that peice, we have the words; " 12 less than the number it's self. I wasn't sure if 2 x's could be in the same equation. Now I know they can.
Above, we established that 'a number' is x.
Now, it's talking about that number again because it says; "The number itself." At first, I thought it was talking about 12 - 12! Then I realized that it's not.
The new equation, after understanding that in the second piece isn't 12 - 12, would be none other than,
x - 2 + 5 = 12 - x
I hope this helps!!
Answer:
The nth term is given by: 
The 30th term is 78.
Step-by-step explanation:
Arithmetic sequence:
The nth term of an arithmetic sequence is given by:

In which
is the first term and d is the common difference between terms.
-9, -6, - 3,0
This means that
. So

30th term:

The 30th term is 78.
