(a-b)² = a² - 2ab + b²
(a+b)² = a² + 2ab + b²

1) (a-5)² = a² - 10a + 25
2) (a+0,5)² = a² + a + 0,25
3) (1-b)² = 1 - 2b + b²
4) (0,7m+n)² = 0,49m² + 1,4mn + n²
5) (6x-10y)² = 36x² - 120xy + 100y²
6) (2х⁴+3у³)² = 4х⁸ + 12х⁴у³ + 9у⁶

miraitan 1) a - 5 = a ^2 - 10a + 25
2) a + 0.5 = a^2 + a + 0.25
3)1 - b= 1 - 2b+ b^2
4)0.7m + n = 0.49m^2+ 1.4mn + n^2
5)6x - 10y= 36x^2- 120xy + 100y^2
6)2x^4 + 3y^3= 4x^8 + 12x^4y^3+ 9y^9
