Объяснение:
1) (а+2)^2 = а^2 + 4а + 4
2) (6-х)^2 = 36 - 12х + х^2
3) (1/2а + b)^2 = 1/4a^2 + ab + b^2
4) (3x - 4)^2 = 9x^2 - 24x + 16
5) (5m + 3n)^2 = 25m^2 + 30mn + 9n^2
6) (0.1a + 10b)^2 = 0.01a^2 + 2ab + 100b^2
7) (6x - 1/3y)^2 = 36x^2 - 4xy + 1/9y^2
8) (n^2 +1)^2 = n^4 + 2x^2 +1
9) ... = 8a^2 - 13b^2 - 6ab
10) ... = 3y^2 + y - 60
