Question

8х(х+у+с)-8у(х-у-с)-8с(х-у-с)

Answer 1

Ответ:

8x^2 + 8xy + 8xc -8xy + 8y^2 + 8yc -8xc + 8yc + 8c^2 = 8x^2 + 8y^2 + 8c^2 + 16yc

Объяснение:

8x^2 - восемь икх во-второй степени.

8xy и -8xy; 8xc и -8xc - являются противоположными, поэтому взаимно уничтожаются.

Answer 2

The expression you've given is:

8x(x + y + c) - 8y(x - y - c) - 8c(x - y - c)

To simplify this expression, you can distribute the constants and then combine like terms:

= 8x(x + y + c) - 8y(x - y - c) - 8c(x - y - c)

Now, distribute the constants:

= 8x^2 + 8xy + 8xc - 8yx + 8y^2 + 8yc - 8cx + 8cy - 8c^2

Now, combine like terms:

= 8x^2 + 8xy + 8xc - 8yx + 8y^2 + 8yc - 8cx + 8cy - 8c^2

The terms with opposite signs and the same variables cancel each other out:

= 8x^2 + 8xy + 8y^2 + 8c(x - y) - 8c^2

So, the simplified expression is:

8x^2 + 8xy + 8y^2 + 8c(x - y) - 8c^2
