x^{3} - 27

Solution steps

(x - 3) (x^{2} + 3 x + 9)

Distribute parentheses

= x x^{2} + x \cdot 3 x + x \cdot 9 - 3 x^{2} - 3 \cdot 3 x - 3 \cdot 9

Simplify

x x^{2} + x \cdot 3 x + x \cdot 9 - 3 x^{2} - 3 \cdot 3 x - 3 \cdot 9 : x^{3} - 27

= x^{3} - 27

- 2 \cdot (- 1)

(x - 3) (x - 5)

(- x + 1)^{2}

(2 x - 1) (2 x + 1)

(x - 6) (x - 6)
