Question

Представьте в виде многочлена​

Answer 1

1) (p + 8)² = p² + 16p + 64

2) (10x – 3y)² = 100x² – 60xy + 9y²

3) (x – 9)(x + 9) = x² – 81

4) (4m + 7n)(7n – 4m) = 49n² – 16m²

Answer 2

Ответ:

Всё просто.

Объяснение:

1. (p+8)^2=p^2+16p+64

2. (10x-3y)^2=100x^2-60xy+9y^2

3. (x-9)(x+9)=x^2-9^2=x^2-81

4. (4m+7n)(7n-4m)=4m·7n-4m·4m+7n·7n-7n·4m=49n^2-16m^2+4m·7n--7n·4m=49n^2-16m^2
