Question

write two identities
​

Answer 1

Answer:

The standard algebraic identities are:

(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)

Answer 2

Answer:

-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)
