The answer is A.All real numbers except -2.
Answer:
x=1.3288 or -1.1288
Step-by-step explanation:
Given 
Subtract 4x from both sides
Since we can factor out 2 from whole equation, let's factor out 2.
Divide with 2 on both sides
We got the quadratic equation, we can solve for x using quadratic formula.
