### Re: Simplify the following:

Let me know how you do.

If you need it:

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

### Re: Simplify the following:

I dont understand  how you got -x^2 +1. As the numerator.

Please, let me know how you got it.
Thanks

### Re: Simplify the following:

Hi;

I did not get that as the numerator. I got x + 1 as the numerator. I just multiplied. Do you need help with that?

### Re: Simplify the following:

We have:

We use FOIL to multiply it.

F means First, so we take the first term of each one and multiply them.

But sir, I think the negative sign is affecting the 'X' and not its power, please could you explain?

### Re: Simplify the following:

Errr okay, I understand it now,  any number raising to the power zero is 1 therefore the 1 should take the sign of the x, Because is the x that makes the 1. I am right sir?
