I see what happened.
Why did your "-7x - 7x" from the fourth line vanish mysteriously?

Once that is corrected, you should obtain the required 16x.
Anyway, one more point.
When writing square for the second line, include brackets.
(x - 7)² and (x + 1)² should be written rather than x - 7 ² and x + 1 ² even though I know that you have attempted to put the square symbol away from the 7 and the 1.
