I'm assuming you are talking about polynomials.
For example, I have x^2 + 2x + 1, and I want to add 2x^2 + x + 2
Then the like terms here are:
x^2 and 2x^2, 2x and x, 1 and 2, they are quadratic, linear and constant, respectively.
Domain of 2(x + 5) is all real numbers.
The sequence is given as follow

,

When finding the pattern of a sequence, we can try to work out whether there is a common difference or a common ratio between each term. We try by finding a common ratio

<h2>
Coordinate of mid point = (1,0)</h2>
Step-by-step explanation:
Given points are (-6,3) and (4,-3)
,
and 
Coordinate of mid point 

=(1,0)
(15, -8) :)
From C to midpoint you do (+10, -7), so you have to do that again to get to D
