Question

all the identities of polynomials​

Answer 1

$\mathfrak{The\:Answer\:is}$

(a+b)^2 = a^2 + 2ab + b^2

(a+b)(c+d) = ac + ad + bc + bd

a^2 - b^2 = (a+b)(a-b) (Difference of squares)

a^3 (+-) b^3 = (a (+-) b)(a^2(-+) ab + b^2) (Sum and Difference of Cubes)

x^2 + (a+b)x + AB = (x + a)(x + b)

if ax^2 + bx + c = 0 then x = ( -b (+-)(b^2 - 4ac) ) / 2a (Quadratic Formula)
