4(a2-b2)2-8ab(a2-b2)-5a2b2 please help me

Step-by-step explanation:

First, solve the square binomial.

Now, distribute the 4 and 8ab respectively.

Combine like terms. (I'll group them so that you can see them more clearly)

(2a²-2b²+a²b²)(2a²-2b²-5a²b²)

Step-by-step explanation:

4(a²-b²)²-8ab(a²-b²)-5a²b²

Let's replace 2(a²-b²)= m and a²b²=n for simplicity

then we have

Now we can replace m and n with initial values:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
