Question

write any 4 identities​

Answer 1

The standard algebraic identities are:

(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)

Answer 2

Answer:

• (a+b) ² = a²+b²+2ab
• a²- b² = (a+b) (a-b)
• (a+b+c) ² = a²+b²+c²+2ab+2bc+2ca
• (a+b) ³= a³+b³+3ab(a+b)
