Answer 1

Explanation:

Wanda was a poor Polish girl who had no American friend. In her school, her classmates Peggy and Maddie made fun of her funny name and her blue dress that she wore every day. But, she did not respond to them and remained silent and serious. She walked alone with dull eyes and hitched her shoulders in a funny way.

Answer 2

Answer:

Explanation:

(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.
