Answer 1

Respuesta:

Explicación paso a paso:

(a-3b)² = (a)² - 2.(a).(3b) + (3b)² = a² - 6ab +9b²

(5x - 3y²)² = (5x)² - 2.(5x).(3y²) +(3y²)² = 25x² - 30xy² + 9y⁴

(3x + y²)² = (3x)² + 2.(3x).(y²) + (y²)² = 9x² + 6xy² + y⁴

(5 - 7z)²= (5)² - 2.(5).(7z) + (7z)² = 25 - 70z + 49z²

(1/4x - 1/2)² = (1/4x)² - 2(1/4x).(1/2) + (1/2)² = 1/16x² - 1/4x + 1/4

(a²b - 2c)² = (a²b)² - 2.(a²b).(2c) + (2c)² = a⁴b² - 4a²bc + 4c²

(3x - 5y)² = (3x)² - 2.(3x).(5y) + (5y)² = 9x² - 30xy + 25y²

(2 - 3n)² = (2)² - 2.(2).(3n) + (3n)² = 4 - 12n + 9n²

(x + y)² = x² + 2.x.y + y² = x² + 2xy +y²

(4 - 1/3m)² = (4)² - 2.(4).(1/3m) + (1/3m)² = 16 - 8/m + 1/9m²
