Simplify the expression 2 (x + 7) (x2 - 3x - 6).

2 (x + 7) (x² - 3x - 6) = 2x³ + 8x² - 54x - 84

Step-by-step explanation:

Simplification is a method used to reduce the complexity or the component parts of an algebraic equation which makes it simpler and easier to understand.

The given equation is: 2 (x + 7) (x² - 3x - 6).

Simplifying the given algebraic equation:

⇒ 2 (x + 7) (x² - 3x - 6)

⇒ (2x + 14) (x² - 3x - 6)

⇒ 2x³ + 14x² - 6x² - 42x - 12x - 84

⇒ 2x³ + 8x² - 54x - 84

2x^3+8x^2-54x-84
