Question

Use FOIL and the distributive property to derive (a-b)^3​

Answer 1

(a-b)^3 =
`\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3`

Explanation:

(a-b)^3 = (a-b)(a-b)(a-b)

According to the perfect cube formula (a-b)^3 =
`\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3`

And there you have it! The perfect cube formula already solved your equation!
