Hey there Cpl., I'm covering the same thing right now in maths, and will do my best to help:
Firstly, you can substitute x=-x, giving you:
From there, rationalise the expression to:
Then, multiply and divide by x:
Then divide again:
After this, use the knowledge that the limit of the quotient is the quotient of the limits, if that makes sense, to do the following:
Again, use the fact that the limit of the difference is the difference of the limits:
Limit of a constant is equal to the constant:
Apply the constant multiple rule:
Cheeky rearrange:
Lim(Constant) = Constant:
Constant/Large number = 0:
Another cheeky rearrange:
Again, Lim(constant) = constant:
Move the limit under the power:
Lim(Diff)=Sum(Limits):
Lim(Constant)=Constant:
Apply constant multiple rule again:
Third cheeky rearrange:
Again, Lim(Constant)=Constant:
Constant/Large number = 0:
Apply constant multiple rule:
Cheeky rearrange:
Lim(Constant)=Constant:
Constant/Big number = 0:
So, therefore:
=-9/2 or -4.5
Hope this helps, took me a while to type it out so may be a bit messy and confusing. Good luck in your exams
Sounds delightful! thank you!

Literally, Maths was slaying me back in high school and this is PTSD-triggering af
Is this a thing now? 29th homework assistance?
Considering we have a lot of school-age members, I don't think why not.
Also because I suck at Maths too lmao
If we only had homework assistance when I was in Highschool. I've might not have been kicked out lol
I've proofread and edited squad members homework assignments on more than one occasion. If it helps them make drills a good leader/squadmate should help out!
