SOLUTION: Do the operations and simplify. 1.(x^2+4x+4/x) * (x^2 - 2x/x^2 -4) 2.(x^2 + 2x - 63/9x^2 +71x +56) * (81x^2 - 64/ 9x^2 +73x

SOLUTION: Do the operations and simplify. 1.(x^2+4x+4/x) * (x^2 - 2x/x^2 -4) 2.(x^2 + 2x - 63/9x^2 +71x +56) * (81x^2 - 64/ 9x^2 +73x - 72)

Question 111456: Do the operations and simplify.
1.(x^2+4x+4/x) * (x^2 - 2x/x^2 -4)

2.(x^2 + 2x - 63/9x^2 +71x +56) * (81x^2 - 64/ 9x^2 +73x - 72)

........ I guess your equation should be writen this way

........ in first term, write
as then group first two and second two terms

........factor out
........reduce and , then and in nominator and denominator

........reduce and
finaly, you will have:
........

2.......
first we can do some factorization:
look first this expression:

Replace with and group the first two terms together
and the last two terms together like this:
��

factor a out of the first group and factor a out of the
second group
�� factor a out
and you will have:

then, look at this expression:
Replace with and group the first two terms together
and the last two terms together like this:
��
factor a out of the first group and factor a out of the second group
�� factor a out
and you will have:

then, this expression we can write as

at the end, take a look at this expression:

Replace with and group the first two terms together
and the last two terms together like this:
��
factor a out of the first group and factor a out of the second group
�� factor a out
and you will have:

now, substitute all of this in :

...reduce
