Question

tell all algebric identites ​

Answer 1

Answer:

Standard Algebraic Identities List

Identity I: (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)

Answer 2

Answer:

(a+b)²= a²+2ab+b²

(a-b)²= a²-2ab+b²

(a+b)(a-b)= a²-b²

(x+a)(x-b)= x²+(a+b)x+ab

(a+b+c)²= a²+b²+c²+2ab+2bc+2ca

(a+b)³= a³+b³+3ab(a+b)

(a-b)³= a³-b³-3ab(a-b)

a³+b³+c³-3abc= (a+b+c)(a²+b²+c²-ab-bc-ca)
