Question

formula of alpha cube + beta cube ​

Answer 1

Answer:

Step-by-step explanation:

(a + b)^3 can be written as,

(a + b) * (a + b) * (a + b)

Let's multiply the first two terms first.

[ (a +b) * (a + b) ] * (a + b)

[ a*a + a*b + b*a + b*b] * (a + b)

(a^2 + ab + ab + b^2) * (a + b)

(a^2 + 2ab + b^2) * (a + b)

Note :The term in the first parenthesis is the formula of (a + b) ^2 = (a + b) * (a + b)
