    Answer:

    By the distributive property we know that

    a

    (

    b

    +

    c

    )

    =

    a

    b

    +

    a

    c

    ,

    therefore:

    2

    x

    (

    x

    2

    +

    4

    x

    2

    )

    =

    2

    x

    x

    2

    x

    4

    x

    2

    .

    Continuing:

    2

    x

    x

    2

    x

    4

    x

    2

    =

    2

    x

    2

    8

    x

    2

    2

    =

    2

    x

    2

    4

    x

    2

    .

    Combining like terms:

    2

    x

    2

    4

    x

    2

    =

    6

    x

    2

    .

    We can now subtract the two terms:

    (

    4

    x

    2

    +

    3

    x

    1

    )

    2

    x

    (

    x

    2

    +

    4

    x

    2

    )

    =

    (

    4

    x

    2

    +

    3

    x

    1

    )

    (

    6

    x

    2

    )

    ,

    and we obtain:

    2

    x

    2

    +

    3

    x

    1

    .
