Question

identify the given expression - x2 + y2 + z2 + xyz
​

Answer 1

Answer:

=AL=539.

540 वा = 21= 28

BA 32L1 = १62 - २७२ HUNO = 12-= 13AL=538

RT=26

BA= 261

Answer 2

Step-by-step explanation:

=AL=539.

540 T 21- 28

BA 32L1 R62 - 0R HUNO = 12-

13AL=538

RT-26

BA 261

(x + y)2 = x2 + 2xy + y2

(x – y)2 = x2 – 2xy + y2

and x2 – y2 = (x + y) (x – y)

and their use in factorisation. In this chapter, we shall start our study with a particular type of algebraic expression, called polynomial, and the terminology related to it. We shall also study the Remainder Theorem and Factor Theorem and their use in the factorisation of polynomials. In addition to the above, we shall study some more algebraic identities and their use in factorisation and in evaluating some given expressions.
