Here is a list of Algebraic formulas –

a2 – b2 = (a – b)(a + b)

(a + b)2 = a2 + 2ab + b2

a2 + b2 = (a + b)2 – 2ab.

(a – b)2 = a2 – 2ab + b2

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

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

(a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)

Answer:

(a+b) 2=a2+2ab+b2

(a+b) 2+(a-b) 2=2(a2+b2)

(a+b) 2-(a-b) 2=4ab

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

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