So let's see how to do it properly with an example: Start with: x2+ 6x + 7 ("b" is 6 in this case) Complete the Square: x2+ 6x + +7 6 Also subtract the new term Simplify it and we are done. x2+6x + ( ) +7-9 7 ) (x + 2)2 + 7-9 = (x+3)2 - 2 The result: x2 + 6x + 7 = (x+3)2 - 2 And now X only appears once, and our job is done!
