Question

-1,5(x+y)+x(x+y)-y(x+y)+(x+y)

Answer 1

Пошаговое объяснение:

-1,5(x+y)+x(x+y)-y(x+y)+(x+y)=

=-1,5x-1,5y+x^2+хy-xу-y^2+x+y=

=х^2-у^2-0,5х-0,5у

Answer 2

Let's simplify the expression step by step:

-1.5(x+y) + x(x+y) - y(x+y) + (x+y)

First, let's distribute the terms:

-1.5x - 1.5y + x^2 + xy - yx - y^2 + x + y

Next, let's simplify and combine like terms:

x^2 - y^2 + x - 1.5x + xy - yx - 1.5y + y

Simplifying further:

x^2 - y^2 - 0.5x - 0.5y + xy - yx

Since xy is the same as yx, we can combine these terms:

x^2 - y^2 - 0.5x - 0.5y + 2xy

So the simplified expression is:

x^2 - y^2 - 0.5x - 0.5y + 2xy
