1) (2x+2)(3x-1) = 6x^2 + 4x - 2.............ANS
---------------------------------------...

2) Length L = (x^2 - 2x - 2)/(x-2)

........................(x-2)(x+1)
.....................= -------------
.............................(x-2)

.....................= (x+1)...............................ANS
---------------------------------------...

3) Total Area = 2x^2 + x + 3
Area of Dining Room = 2x^2 - 2x
Area of Living Room = Total Area - Area of Dining Room
.....................................= 2x^2 + x + 3 - (2x^2 - 2x)
.....................................= 2x^2 + x + 3 - 2x^2 + 2x
.....................................= 3x + 3
.....................................= 3 (x+1)......................................
