The answer is in the attachment below. Open it up in a new window to see it in full.
The secret to solving this problem lies in completing the square.
It is going to end up as x = x + 1, which is not possible even if x = 0. so solution does not exist.
When solving the equation 2 1 x + 2 1 x = x + 1 , we simplify and find that it leads to a contradiction ( 0 = 1 ). Therefore, there is no solution for x .
