x^2(x-4)
x^3(2x+5)
x(x^2 - 3x + 4)
(x-7)(x-3)
(x+2)(x+4)
(x+3)(x+8)
x³ - 4x² =
= x²(x - 4)
2x⁴ + 5x³ =
= x³(2x + 5)
x³ - 3x² + 4x =
= x(x² - 3x + 4)
x² - 10x + 21 =
= x² - 3x - 7x + 21
= x(x - 3) - 7(x - 3)
= (x- 7)(x - 3)
x² + 6x + 8 =
= x² + 4x + 2x + 8
= x(x + 4) + 2(x + 4)
= (x + 2)(x + 4)
x² + 11x + 24 =
= x² + 8x + 3x + 24
= x(x + 8) + 3(x + 8)
= (x + 3)(x + 8)
