Question

write all the formula of identities​

Answer 1

Step-by-step explanation:

ANSWER ✍️

Identity-I: (a + b) (a + c) (b + c) = (a + b + c) (ab + ac + bc) – abc.

Identity-II: a2 + b2 + c2 = (a + b + c)2 – 2(ab + ac + bc)

Identity-III: a3 + b3 + c3 – 3abc = (a + b + c) (a2 + b2 + c2 – ab – ac – bc)

Identity-IV: (a – b) (a – c) = a2 – (b + c)a + bc.

hope this helps you!!

Answer 2

Identity I

(a+b)2 = a2+2ab+b2

Identity II

(a-b)2 = a2- 2ab+b2

Identity III

a2-b2= (a+b) (a-b)

Identity IV

(x+a) (x+b) = x2+(a+b) x+ab

Identity V

(a+b+c)2= a2+b2+c2+ 2ab+2bc+2ca

Identity VI

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

Identity VII

(a-b)3= a3 -b3-3ab(a-b)

Identity VIII

a3 +b3+c3-3abc
