Hi I am new

Hi I am new to this forums'I am doing my homework right now and I REALLY need help in this 2 problems'please help me'.please..i have test tomorrow and these 2 probs are kinda confusing'please'..btw I am in 11th grade n the subject is pre-calculus

I have just started watching kis desh'my name is Sanjana..and I am from USA'I love prem..he is sooooo hooootttt..can you guys tell me his real name and his birthday😳

The problems are X -Y/ x over y plus y over x (the x over y is only underneath the Y not the X)

And another one is 1+ 1 over c-1 OVER 1- 1 over c-1

Hello Sanjana..

I don't think so you are suppose to put your homework problems to this forum…its to discuss the show…so next time don't do it you are not allowed..i don't know where can you get homework help here but don't post it here…but still since you have test tomorrow I will help you out…

Wow..thats an easy problem….here is the solution…

Okay so first of all find the common denominator for only x over y plus y over x and the common denominator is xy so it would be X –Y/ x² + y² over xy (once again the common denominator is xy)

And then just divide the y/x^2 + y^2 over xy and since its dividing you change the sign and flip so it would be X – Y time XY over x^2 + y^2

after then you multiply and you get X – x(y^2) over x^2 + y^2 and you still have to do everything to X…common denominatior and its X^2 + Y^2 (you know why right..since we multiplied everything it changed)

So after then its: x(x^2+y^2) – x(y^2) over x^2 + y^2 and then distribute and you get x^3 + x(y^2) – x(y^2) over x^2 + y^2 and then xy^2 and –xy^2 cancel out so its x^3 over x^2 + y^2 and that's your answer

Problem # 2:

The common denominator is c-1 for both..all you have to do is multiply…once you multiply c-1 to 1 (both on the top and bottom 1) you should get 1+C-1 (which is C cuz 1-1 is 0) over c-1 divide by c-1-1 (which is C-2 cuz -1-1 is -2) over c-1 and since its dividing its reciprocal…so its C over c-1 times c-1 over c-2 and c-1 (s) cancel out and you are left with c over c-2

I already did all these in pre-calc..its really easy hun...at first its confusing but at the end its easy..even i had it when i was a junior...you are in GT right since you have it in ur junior year..its normally in ur senior year...lol...but i love HS math its pretty easy...i did all these 3 years ago..lol...i am in college and i did this in my freshman year of college...its pretty easy...

ok. i tried..but i'm really bad at writing math in english(you know what i mean). ok so for the first one, you take the reciprocal of the second one, so that makes it :(x-y)/x multiplies by (x)/y+y. so the x's cancel out. so the answer would be (x-y)/(y+y). i dont know if its supposed to be simplified further more. and you can do the same thing for the second one. take the reciprocal of the denominator. so the c-1 will cancel out. hope this helps. 😊

P.S there should be a homework section in IF, so people could like multi-task.

aah welcome to the forum hun!

hi sanjana welcome to the forum, i'm salma.

thank you everybody...i feel welcomed😳
