Complete Question:
<em>Given the functions, 
and 
, perform the indicated operation. When applicable, state the domain restriction.</em>
<em>(f-g)(x)</em>
(f-g)(x) basically means subtract the function g from the function f and put "x" into "x". Since there are no values in place of "x", just "x" itself, we simply subtract function g from function f and that's it.
Doing algebra, we have:
The first answer choice is right,
Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0
Divide both sides by 2:
x^2 - 2 x - 3/2 = 0
Add 3/2 to both sides:
x^2 - 2 x = 3/2
Add 1 to both sides:
x^2 - 2 x + 1 = 5/2
Write the left hand side as a square:
(x - 1)^2 = 5/2
Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)

Answer:
x= 82
Step-by-step explanation:
x + 48 + 50=180( being sum of all triangle)
or, x + 98 =180
or,x= 180-98
x = 82
