tell all identities and were and how to to use them please tell I will mark you as Brainliest (algebra) . where is the question
Answer:
Step-by-step explanation:
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 = (a + b + c)(a2 + b2 + c2 – ab – bc – ca)
WHERE YOU USE THEM IS A SUBJECTIVE QUESTION.IT DEPENDS ON THE FORM OF QUESTION.
FOR INSTANCE IF YOU HAVE A QUESTION LIKE 9 SQUARE-8 SQUARE THEN YOU HAVE TO SEE IT MATCHES WHICH IDENTITY AND YOU HAVE TO USE THAT.HERE THE ANSWER FOR THIS IS a2 – b2= (a + b)(a – b)
