Question

can someone help me understand this step, i am finding the second derivatve using implicit differ.
: (y-(x)(-x/y))/(y^2), how do i simpify this?

Answer 1

\[\frac{y-x\times \frac{-x}{y}}{y^2}\] ?

Answer 2

yes

Answer 3

i am finding the second derivative and i got this far, but i am unsure of how to simplfy in order to get it in the form needed

Answer 4

multiple x times (-x/y) and get x^2/y, then find a common denominator inorder to add the two fractions in the numerator. Finally multply by the reciprocal or y^2 which is 1/y.

Answer 5

1/y^2*

Answer 6

my next goal should be to randomly colorize equations :)
