Hi again xD

Answer 2

hey!
that looks kinda scaryx'D
gimme a moment and i'll right back :)

Answer 3

Thank you <3

Answer 4

Okay I am back!
Let's solve all of them step by step.
Did you try anything so far?
what has been ur approach?:)

Answer 5

My biggest problem starting them is figuring out if it needs to be factored or if we can start canceling things out right away.

Answer 6

I know that the \[4x ^{2}-y ^{2}\] can't be canceled out unless there is another one just like it.

Answer 7

Okay so ur approach needs to be changed
Now the first thing we will look for in a sum is to SIMPLIFY it first and then see if it can be cancelled okay?

Answer 8

Okay...simplifying means adding the like terms right? And only the like terms in each sequence? (so if I had a like term on top of the fraction and one on the bottom they can't be combined...)

Answer 9

nah simplifying is not just about adding..
By simplification we mean reducing the expression in the simplest form that is in the factor form
Clear so far?

Answer 10

Oh so like division...? I have a tutor that says don't look at fractions as fractions, look at them as division.

Answer 11

(I'm so sorry if I'm making this hard on you)

Answer 12

Well,at a lower level,your tuitor is pretty right
(I mean low level problems)
but what he actually means is that we gotta look at fractions in THE SIMPLEST FORM as just division
in numbers it's simple...but it changes in algebra
First you need to convert the terms in the SIMPLEST form or the FACTOR FORM and then proceed
Take for example
cannot be canceled just yet
but when it is simplified using an identity (hat we used previously) it becomes easy to cacel it out with some other term..


any doubts so far?^-^
dunt worry.....It's not hard on me....we take in knowledge to impart it further and to make productive use f it by helping those who need it:)
