Question

Write the expression as a polynomial, using the corresponding formula for special product: (−y+x)(x+y)

Answer 1

Answer:

x² - y²

Step-by-step explanation:

(-y + x)(x + y)

(x - y)(x + y)

x² - y²

Answer 2

Answer:

____

x^2 - y^2

____

Step-by-step explanation:

(-y+x)(x+y) Can be written as (x-y)(x+y).

(x-y)(x+y)=x^2 - y^2

This formula is called, “difference of squares”

P.S.

A polynomial like x^2 + y^2 is ALWAYS prime.
