This is again a use of FOIL
( 1 x ) 2
This term is expanded into
( 1 x ) ( 1 x )
Multiply the FIRST terms together
(1)(1) = 1
Multiply the OUTER terms together
( 1 ) ( x ) = x
Now multiply the inner terms together
( x ) ( 1 ) = x
Then multiply the LAST terms together
( x ) ( x ) = ( x ) 2 = x
Lastly add the terms together
1 x x + x
= 1 2 x + x
