Because you want to see where it crosses the x axis

So

x^3 + 2 = 0

Rearrange to find x

ohhhhhh thank you very much i was so lost

they have put the (-) symbol outside the root 3 because it is not possible to have the square root of a negative number right?

My teacher just doesn't explain everything she just expects us to know and moves through quickly.
I told my teacher i wasn't understanding the class and she just gave emailed powerpoints she uses in lessons like that's not rlly solving the problem lmao. So I have to teach myself the whole chapter now in the holidays LOVE THAT FOR ME .

yess we'll get through this!!

I made some videos about this topic a few years back which you might find helpful. I should warn you, I do this in a bit of a non-standard way, but I think it's easier to understand and remember.

I am in the exact same boat as you my teacher literally doesn't know what he's doing we have to correct him half the time

I can recommend Corbett maths, Hegarty maths and khan academy youtube channels have been really helpful for me.

also, the support of other people on this website is so helpful

my teacher uses the same powerpoint since the school opened in 2006

i think math is one of those subjects you need to practice until you can do it in your sleep so it should be worksheet based
