01 (x + 5)2 = x2 + 10x + 25 
02 (7a + b)2 = 49a2 + 14ab + b2 
03 (4ab2 + 6xy3)2 = 16a2b4 + 48ab2xy3 + 36x 2y6 
04 (xa+1 + yb-2)2 = x2a+2 + 2xa+1yb-2 + y2b-4 
05 (8 - a)2 = 64 - 16a + a2 
06 (3x4 -5y2)2 = 9x8 - 30x4y2 + 25y4 
07 (xa+1 - 4xa-2)2 = x2a+2 - 8x2a-1 + 16x2a-4 
08 (5a + 10b)(5a - 10b) = 25a2 - 100b2

 

Espero t sirvan chaito C:
