Question

All algebraic identies of cube

Answer 1

Answer:

Step-by-step explanation:

(a + b)2 = a2 + 2ab + b. ...

(a – b)2 = a2 – 2ab + b. ...

a2 – b2 = (a + b)(a – b)

(x + a)(x + b) = x2 + (a + b) x + ab.

(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.

(a + b)3 = a3 + b3 + 3ab (a + b)

(a – b)3 = a3 – b3 – 3ab (a – b)
