Question

how many formulas in polynomial​

Answer 1

Answer:

The algebraic identities used in factorising a cubic polynomial are: (a + b)3 = a3 + b3 + 3ab (a + b) (a – b)3 = a3 – b3 – 3ab (a – b)

Answer 2

Step-by-step explanation:

A polynomial expression is the one which has more than two algebraic terms. As the name suggests, Polynomial is a repetitive addition of a monomial or a binomial.

The general Polynomial Formula is written as,

axn+bxn−1+…..+rx+s=0

If n is a natural number, an – bn = (a – b)(an-1 + an-2 +…+ bn-2a + bn-1)

If n is even (n = 2k), an + bn = (a + b)(an-1 – an-2b +…+ bn-2a – bn-1)

If n is odd (n = 2k + 1), an + bn = (a + b)(an-1 – an-2b +…- bn-2a + bn-1)

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