Question

Expand the polynomial.

(-1-2a^2b)(1-2a^2b)

Answer 1

Was it this instead?
`(-1-2a^(2)b)(1-2a^(2)b)`

Answer:

`4a^(4b)-1`

Explanation:

I am assuming your question is this.

`(-1-2a^(2b))(1-2a^(2b))`

Apply the difference of 2 squares formula.

`(a-b)(a+b)=a^(2) -b^(2)`

So then we have.

`(-1-2a^(2b))(1-2a^(2b))=(-2a^(2b))^(2)-1^(2)`

Then simplify.

`4a^(4b)-1`
