Разллжите многочлен на множители ac2 (во второй степени) - ad+c3-cd-bc2+bd = mx2+my2-nx2-ny2+n-m = am2+cm2-an+an2-cn+cn2 = xy2-ny2-mx+mn+m2x-m2n = a2b+a+ab2+b+2ab+2 = x2-xy+x-xy2+y3-y2=

1) ac² - ad + c³ - cd - bc² + bd = a * (c² - d) + c * (c² - d) - b * (c² - d) = (c² - d) * (a + c - b).

2) mx² + my² - nx² - ny² + n - m = x² * (m - n) + y² * (m - n) - 1 * (m - n) = (m - n) * (x² + y² - 1).

3) am² + cm² - an + an² - cn + cn² = m² * (a + c) - n * (a + c) + n² * (a + c) = (a + c) * (m² - n + n²).

4) xy² - ny² - mx + mn + m²x - m²n = y² * (x - n) - m * (x - n) + m² * (x - n) = (x - n) * (y² - m + m²).

5) a²b + a + ab² + b + 2ab + 2 = a * (ab + 1) + b * (ab + 1) + 2 * (ab + 1) = (ab + 1) * (a + b + 2).

6) x² - xy + x - xy² + y³ - y² = x * (x - y²) - 1 * (x - y²) - y * (x - y²) = (x - y²) * (x - 1 - y).
