Answer 1

Ответ:

1) x^2y - z^2x + y^2x - z^2y = xy(x+y)-z^2(x+y)

2) y^4 + 3 - y^2 - 3y^2 = (y-1)(y+1)(y^2-3)

3) p(a+b) - a - b = (b+a)(p-1)

4) 2ax^2 - 6a + x^2 - 3 = (2a+1)(x^2-3)

5) c(x+y) + 7cx + 7cy = 8c(y+x)

6) 64x^3 - 8x^2 - 2 + 16x = 2(8x-1)(4x^2+1)

7) a^2(a-5) - 2a + 10 = (a-5)(a^2-2)
