Question

Give three standard identities ( Algebric Expressions )

Answer 1

Answer:

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

2) a^2 – b^2 = (a + b)(a – b)

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

Answer 2

Answer:

The standard algebraic identities are:

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

(a – b)2 = a2 – 2ab + b2

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
