Ex: (2x + 3y)³ where 2x is the first term, and 3y is the second term

Step:

1) Cube the first term: (2x)³ ⇒ (2x)(2x)(2x) =

2) 3(first term)² (second term) ⇒ 3(2x)²(3y) = 3(4x²)(3y) =

3) 3 (first term) (second term)² ⇒ 3(2x)(3y)² = 6x (9y²) =

4) Cube the last term: (3y)³ = (3y)(3y)(3y) =

Answer: 8x³ + 36x²y + 54xy² + 27y³
