7x(x² + 8)

4x(x² - 14)

x(7x² - 56)

7x(x² - 8)

4x²y - 8x² = 4x² (y - 2)

4x²- x³ = 4x²(1 - x)

5x²y – 10x³ y = 5x²(1 – 2x)

x²- 3x² y = x²(1 - 3y)

(x - 3)(x + 2)

(x -3 )(x - 2)

(x - 6)(x + 1)

x² – 4x – 12 = (x - 6)(x - 2)

x² + x – 2 = (x + 2)(x - 1)

x² + 3x + 2 = (x + 2)(x + 1)

x² – 7x – 8 = (x - 8)(x +1)
