This is for my daughter.

find the product of

x^2 -4/5 X x + 2/x - 2

could you please show us the work so we can try to understand how it works?

1. [(x^2-4)/5] * (x+2)/(x-2) ??? maybe???

(x+2)(x-2)/5 * (x+2)/(x-2)

(x+2)^2 /5
or
(x^2 + 4 x + 4)/5

2. Use parentheses to make things easier.

[(x^2)-(4x/5)]*[(2/x)-2]

[(x^2)*5/5-(4x/5)]*[(2/x)-2*x/x)

(5x^2-4x) * (2-2x)
--------- ----
5 * x

Multiply through to get:

10x^3+18x^2-8x
--------------
5x
