FAQ's on a^3 - b^3 Formula a³ - b³ formula is read as a cube minus b cube. Its expansion is expressed as a³ - b³ = (a - b) (a² + ab + b²).

What is A minus B cube?

The formula is also known as the cube of the difference between two terms. To find the formula of (a - b)³, we will just multiply (a - b) (a - b) (a - b). (a - b)³ = (a - b)(a - b)(a - b) = (a² - 2ab + b²)(a - b) = a³ - a²b - 2a²b + 2ab² + ab² - b³.

What is a cube minus B cube minus C cube?

Answer: (A Cube + B Cube + C Cube) - 3abc. Before you understand a3 + b3 + c3 - 3abc = (a + b + c)(a2 + b2 + c2 - ab - bc - ca), Step-by-step explanation: please mark as brainlist.

How do you expand your AB 2?

Expansion of (a ± b)²

1. = a2 - 2ab + b2. Therefore, (a + b)2 + (a - b)2. = a2 + 2ab + b2 + a2 - 2ab + b2.
2. = 2(a2 + b2), and. (a + b)2 - (a - b)2. = a2 + 2ab + b2 - {a2 - 2ab + b2}
3. = 4ab. Corollaries: (i) (a + b)2 - 2ab = a2 + b2.
