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.

Answer:
B
Step-by-step explanation:
Givens
a = 2 sqrt(3)
b = 3 sqrt(2)
c = ?
Formula
a^2 + b^2 = c^2
Solution
- (2sqrt(3))^2 = 2*2 * sqrt(3)*sqrt(3)
- (2sqrt(3))^2 = 4 * 3
- (2sqrt(3))^2 = 12
- (3sqrt(2))^2 = 3 * 3 * sqrt(2)*sqrt(2)
- (3sqrt(2))^2 = 9 * 2
- (3sqrt(2))^2 = 18
(2sqrt(3)^2 + 3sqrt(2)^2 ) = c^2
4*3 + 9*2 = c^2
12 + 18 = c^2
c^2 = 30
sqrt(c)^2 = sqrt(30)
c = sqrt(30)
