Answer 2

HI MATE!!!!!

HERE IS YOUR ANSWER

✨✨✨❤❤✨✨✨

The formula is (a+b)^3 = a^3 + 3a^2b + 3ab^2 - b^3.

You convert it to (a-b)3 = a3 - 3ab (a-b) - b3 .

for an illustration...

you take the drawing of the formula

(a+b)3 = a3 + 3a^2b + 3ab^2 + b3

from above and replace 'a' by the difference (a-b)
