Cube of Binomial:
Example:
(x + 2)³
First term: x
Last term: 2
Steps:
1) Cube the first term
= x³
2) 3 (first term)² (last term)
3 (x)² (2)
= 6 x²
3) 3 (first term) (last term)²
3 (x) (2)²
(3x) (4)
= 12x
4) Cube the last term
(2) ³ = (2) (2) (2)
= 8
5) Combine the result of each step:
x³ + 6x² + 12x + 8
