Question

Реши используя ФСУ

(x – 2)² =

(y + 6)(y – 6) =

(4 – a)² =

(b – 3)(b² + 3b + 9) =

(b² – 3)(3 + b²) =

(- 3y + 1)² =

(x² – 4x + 16)(x + 4) =

(4 – 3a)(3a + 4) =

​

Answer 1

Объяснение:

(x – 2)² = x² - 4x + 4

(y + 6)(y – 6) = y² - 6²

(4 – a)² = 16 - 8a + a²

(b – 3)(b² + 3b + 9) = (b - 3)(b + 3)² = (b² - 3²)²

(- 3y + 1)² = 9y²- 6y + 1
