Ultimately then, validity is of paramount importance because it refers to the degree to which a resulting score can be used to make meaningful and useful inferences about the test taker

Find the GCF of the 3 given numbers (2,20,and 50) in this case it 2
divide the whole equation by 2
You are left with:
2(x^2+10x+25)
From here simply factor it.
ask yourself, what 2 numbers would multiply to make 25 but add to make 10
5 x 5=25
5+5=10
so 5 and 5...
(x+5)(x+5)
Now you need to break the expression: x^2+10x+25 into groups
like this:
(x^2+5x)+(5x+25)
Find the GCF of each number set (5 and 1, 5 and 25 )
divide by the numbers you get. In this case for 5 and 1 it is just x divide both numbers by x to get :
x(x+5)
For 5 and 25 it is 5 so you get:
5(x+5)
Combine the 2 expressions we got.
x(x+5)+5(x+5)
Factor out the equation and you get your final answer
2(x+5)(x+5) or it can also be written as 2(x+5)^2
= 2*(x^2+ 10x+25)
= 2(x+5)^2.
The final answer is 2(x+5)^2.

Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
Overall, the steps for algebraically finding the range of a function are:
Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x).
If you can't seem to solve for x, then try graphing the function to find the range.
