Question

How can I learn all the identities of polynomials?

Answer 1

Answer:

Polynomial identities are equations that are true for all possible values of the variable. For example, x²+2x+1=(x+1)² is an identity.

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)
