Answer 1

Ответ:

1.

а) (а+р)^2 = а^2 + 2ар + р^2

б) (b-q)^2 = b^2 - 2bq + q^2

в)(x^2-8c)^2 = x^4 - 16cx^2 + 64c^2

2.

a) (x-4c)^2 = x^2 - 2x×4c + (4c)^2= x^2 - 8cx + 16c^2

б) (3a-p)^2 = (3a)^2 - 2×3a×p + p^2= 9a^2 - 6ap + p^2

в) (2a-3x^3) = (2a)^2 - 2×2a×3x^3 + (3x^3)^2= 4a^2 - 12ac^3 + 9x^6

3.

16c^2 - (5x - 4c)^2

16c^2 - (25x^2 - 40cx + 16c^2)

16c^2 + 25x^2 + 40cx - 16c^2

- 25x^2 + 40 cx

4.

(x-3)^2 = (x-1)(x+3)

x^2 - 6x + 9 = x^2 + 3x - x - 3

- 6x - 3x + x = - 3 - 9

- 8x = - 12

x = 3/2
