Vous pourriez me faire les 2 exercices en entier ?!

A = 36-25x² = 6² - (5x)² = (6-5x)(6+5x) 
B = 9(x-10/3)² 
C = 2i(i+1)+2i(2+i) = 2i(i+1+2+i) = 2i(2i+3) 
D =b² -10b +25 = (b-5)² 
E = (2-x)² + (2-x)(9+x) = (2-x)(2-x+9-x) = 11(2-x) 
F = (5x-1)² -81 = (5x-1+9)(5x-1-9) = (5x-8)(5x-10) = 5(x-2)(5x-8) 
G = (7d+2)² - (3d+4)² = (7d+2-3d-4)(7d+2+3d+4) = (4d-2)(10d+6)
