Thank you for the video... My kid understands and I was able to teach her...

Are you thinking of an example like this [(x + 2)^3] / x^2 in which you have a binomial taken to a power in the numerator or denominator?

@MrCaryMath

In such a case, would you have to leave the answer with the (x+2)^3, or would it be legal to expand the equation to have x^3 + 2^3 = x^3 + 8 ...? I think it's the former, but am a bit rusty on my exponents. Great video, really clear and easy to understand. Thanks! :)

[MrCaryMath]

@Bellatrikss If the final answer was (x + 2)^3 it is usually fine to leave the answer just as you have it in factored form. If you did choose to to multiply it out, be careful, you would not get x^3 + 8, because you would need to multiply (x + 2)(x + 2)(x + 2).

Thanks a lot man! Great video!

I only have a doubt: Do you know what to do when you have a sum or a subtraction in the numerator or denominator?
