How do you implicitly differentiate: sqrt(xy)=x^2y+1
Furkat [3]
Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression 
<span>sqrt(xy)=x^2y+1 is

sqrt x * 0.5 y ^-0.5 dy + </span>sqrt y<span> * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx 
dy (x^2 - 0.5 (</span>x/y) ^0.5) = dx (2xy  - 0.5 (y<span>/x)^0.5) 
dy/dx = </span>(2xy  - 0.5 (y/x)^0.5) / (x^2 - 0.5 (<span>x/y) ^0.5)</span>

Can someone please tell me if i am right?
pentagon [3]
Second one is correct, that is an identity.

Third one is a contradiction:
6x - 15 = 3 * (2x - 6)    ------>    6x - 15 = 6x - 18

Fourth one:
5x - 3 * (x - 4) = 2 * (x - 6) ---> 5x - 3x + 12 = 2x - 12 ---> 2x + 12 = 2x -12
So this is a contradiction as well.
