Ba lần kháng chiến chống Mông – Nguyên thắng lợi nhờ những nguyên nhân chính sau:
1; Q(x) = -7x - 3x^2 - 5x^3 + 6 + 8x^2 - 2x^3 + 2x - 9
Q(x) = (-7x + 2x) + (-3x^2 + 8x^2) - (5x^3 + 2x^3) - (9- 6)
Q(x) = -5x + 5x^2 - 7x^3 - 3
Q(x) = -7x^3 + 5x^2 - 5x - 3
2; Bậc của đa thức trên là 3; hệ số tự do là - 3
1) Q(x) = -7x - 3x² - 5x³ + 6 + 8x² - 2x³ + 2x - 9
= (-5x³ - 2x³) + (-3x² + 8x²) + (-7x + 2x) + (6 - 9)
= -7x³ + 5x² - 5x - 3
2) Bậc của đa thức Q(x) là 3
Hệ số tự do của Q(x) là -3
