You'll need to isolate x from the rest of the problem if set to zero. First, begin off by subtracting 2 to the other side (subtract because the 2 is positive due to the plus sign, if it was a minus 2, you'd add). Then you have 4x = -2. Now, you divide each side of the equation by 4 (since 4 is being multiplied by x, you will do the opposite of that and divide to isolate x). YOu will then get,
x = -2/4 = -1/2 ..That's your answer.

To solve for x, Subtract 2 on both sides and divide by 4 on both sides, then simplify. Answer is x = - 1/2.
To factor, note that 2 is a common factor, so 2 (2x + 1).

You could graph the solution. For instance X=-1, X=1, X=-5, X=5

if there is no = sign there is nothing you can do.
well, i guess you could factor out 2 to get 2(2x+1)

Who cares? you'll never use a problem like that in life..
