Question

simplify x/(x^2-y^2)-y/(x^2-y^2)

Answer 1

= ( x - y ) / (x-y) ( x+y)
Can you continue?

Answer 2

i would cancel the x-y leaving me with 1/x+y right?

Answer 3

how did u do that because i have several subtration ones i dont understand

Answer 4

Memorize the essential formula:
x² - y² = ( x - y) ( x + y)

Answer 5

ok so as long as the bottom is the same i can subtract them and then factor it out right

Answer 6

That's the ultimate basic rule as 2/2 - 1/2 = 1/2

Answer 7

ok thank you so much for helping me and i think it makes sense now to me on how you were able to get the answer

Answer 8

I'm glad you ask, otherwise I don't know where to explain :)

Answer 9
