The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.
For the first one you get:



For the second one you get:



Which mean that The 2 equations are not equal, because

Hope this Helps! :D

To complete the square, the same value needs to be added to both sides

To complete the square, Add 4 on both sides of the equation

Use a²+2ab+b²=(a+b)² to factor the expression

Move the constant to the right-hand side and change its sign

Calculate the difference

And, We are done solving!!~
