 1)    [B]:  " x² − 10x  + 25 " .
_____________________________________________________
 2)   [D]:  " 
x² +  10x + 25 " .
_____________________________________________________
Note:
_____________________________________________________
1)  (x − 5)² =  (x − 5) (x − 5) = x² − 5x − 5x + 25 = x² − 10x + 25 .

2) (x + 5)² =  (x + 5) (x + 5)  = x² + 5x + 5x + 25  = x² + 10x + 25 .
