Question

3) (х - у) (x-y)(х - у);​

Answer 1

Ответ:

(x-y) (x-y) (x-y)

(x-y)^3

x^3-3x^2y+3xy^2-y^3

Answer 2

It seems like you've provided an expression "(х - у) (x-y)(х - у)" which appears to be a multiplication of several terms. However, it looks like there might be some confusion in the notation you used. It appears that you are using the Cyrillic alphabet characters "х" and "у" instead of the Latin alphabet characters "x" and "y".

Let's assume you meant to write the expression in standard mathematical notation using Latin alphabet characters:

The expression "(x - y) (x - y) (x - y)" can be simplified using the distributive property of multiplication, also known as FOIL (First, Outer, Inner, Last) method. This involves multiplying each term in the first set of parentheses with each term in the second set of parentheses and then combining like terms:

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

If you'd like any specific further steps or simplifications, or if you had something else in mind, please provide more context or details.
