Question

22fgh by -11 divide the following ch name algebraic expression of identities ​

Answer 1

Answer:

Step-by-step explanation:

What is algebraic expression?

Ans:- An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). 

Ex:- 3x + 4y – 7,  4x – 10, etc.

Solution:-

22fgh /(-11)

i.e equal to -2fgh

Answer is -2fgh

Identies are :-

Identity I: (a + b)2 = a2 + 2ab + b2

Identity II: (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)

Identity VII: (a – b)3 = a3 – b3 – 3ab (a – b)

Identity VIII: a3 + b3 + c3 – 3abc = (a + b + c)(a2 + b2 + c2 – ab – bc – ca)
