You need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.
Step-by-step explanation:
Since the functions f(x) and g(x) are missing in the question, I will explain it with my own example and you can solve it with your functions.
Let f(x)= 2x^2+3x+4
and g(x) = 4x^2+9x-6
We need to find f(x)-g(x)
Solving:
f(x)-g(x)=2x^2+3x+4-(4x^2+9x-6)
f(x)-g(x)=2x^2+3x+4-4x^2-9x+6
f(x)-g(x)=2x^2-4x^2+3x-9x+4+6
f(x)-g(x)=-2x^2-6x+10
So, you need to change the sign of all terms of g(x) and then combine the like terms and simplify your answer.

The given expression is a perfect square trinomial.
<h3>
How to classify the given expression?</h3>
Here we have the expression:

Notice that we can rewrite it as:

Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:

We will have:

Which is in fact, a perfect square trinomial.

Answer:
e. 1/(49n² +7n)
Step-by-step explanation:

Answer:
y = x + 7
Step-by-step explanation:
3y - 3x = 21
3y/3 - 3x/3 = 21/3
y = x + 7
Answer:
5/4
Step-by-step explanation:
, open the bracket
3=28-14u-6u
Collect like terms
3-28=-14u-6u
-25 =-20u
Divide both side by -20
u=-25/-20. Minus sign will cancel each other and reduce to the lowest term
u=5/4
