Question

x-{y-(x-y)}+x{x+y-(x-y)}​

Answer 1

Answer:

(x+y)(2x+y)+(x+2y)(x−y)

=x(2x+y)+y(2x+y)+x(x−y)+2y(x−y)

=2x

Answer 2

Answer:

Step-by-step explanation:

x - { y - ( x - y ) } + x { x + y - ( x - y ) }

= x - { y - x + y } + x { x + y - x + y } (∵ - × - = + & - × + = - )

= x - { 2y - x } + x { 2y }

= x - 2y + x + 2xy

= 2x - 2y + 2xy or 2 ( x - y + xy ) is the answer
