Question

write all the algebric identities​

Answer 1

Step-by-step explanation:

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)...

Answer 2

${\underline{\underline{\mathfrak{Identities }}}}$

$\sf{=>(x + y)(z + a) = xz + \: xy \: + yz + \: ya}$

$\sf{= > ({a \: + b})^{2} = {a}^{2} + 2ab + {b}^{2}}$

$\sf{ = > ({a \: - b})^{2} = {a}^{2} - 2ab + {b}^{2}}$

$\sf{= > (a \: + b)(a - b) = {a}^{2} - {b}^{2}}$
