do it by yourself first. when you get stuck, ask here
Hi guys,
I have a Math final worth 100% of my grade and have been knee deep in my text book for the past 2 weeks. I went to the copy centre beside my University and they had old copies of finals, and my friend who did the Math final last year said she used the old exams to study and they're almost identical each year (except obviously the values of the numbers changed etc).
I scanned the most recent exam from last term and would really appreciate if someone could outline the basic way to deal with the questions. Anyway this is the exam PDF, any form of help is appreciated.
Exam url: Exampdf.pdf
Appreciate any advice/help. Thank you!
Thanks guys. Right now I'm studying up on factorization of polynomials but for example, I know that d) and e) in Part 3 can be cross multiplied cause of the equal sign, but when the operations are addition/multiplication like in Part 4, what are the steps for that? For now will focus on understanding part 1. Thanks again
edit: ok so I get to Part 2 and on a) I get as far as this "(-8y^3)(-y^6)" but then the exponent outside the bracket is ^-2, do I inverse it and make it the denominator? ugh my brain is so scrambled
K guys haha, I'm slowly getting these. In part 4, however, I'm stumped. I know that the fractional equations in Part 3 can be cross multiplied but in Part 4 I have no idea what steps to take. I'm gonna keep trying to learn it but any clarification would be awesome. Thanks
I'll do some of the first one for you.
Now we have to find a common factor in the denominator. Factorise to make it more simple.
Difference of Perfect Squares
The common factors are
Cross out
You are left with:
hope i did this right.
So basically find common denominator by factorising if you need to then simplify away!
