Question

9 identites of polynomials

Answer 1

Answer:

I know only eight please forgive me.................

Step-by-step explanation:

Identity I: (a + b)^2 = a^2 + 2ab + b^2

Identity II: (a – b)^2 = a^2 – 2ab + b^2

Identity III: a^2 – b^2= (a + b)(a – b)

Identity IV: (x + a)(x + b) = x^2 + (a + b) x + ab

Identity V: (a + b + c)^2 = a^2 + b^2 + c^2 + 2ab + 2bc + 2ca

Identity VI: (a + b)^3 = a^3 + b^3 + 3ab (a + b)

Identity VII: (a – b)^3 = a^3 – b^3 – 3ab (a – b)

Identity VIII: a^3 + b^3 + c^3 – 3abc = (a + b + c)(a^2 + b^2 + c^2 – ab – bc – ca)
