Find dy/dx by implicit differentiation. x2 − 8xy + y2 = 8
almond37 [142]
We have that

x² − 8xy + y²<span> = 8
</span>2x-8y-8x(dy/dx)+2y*(<span>dy/dx)=0
</span>8x(dy/dx)-2y*(dy/dx)=2x-8y
[8x-2y]*(dy/dx)=2x-8y
(dy/dx)=[2x-8y]/[8x-2y]
(dy/dx)=2*[x-4y]/2*[4x-y]
(dy/dx)=[x-4y]/[4x-y]

the answer is
(dy/dx)=[x-4y]/[4x-y]

Answer:

The answer is x=3.

Step-by-step explanation:

Given:

\frac{x-3}{14}=0

Multiply by 14 on both the side, it gives

\frac{x-3}{14}\times 14=0\times 14\\ x-3=0.

Now we add 3 on both sides.

x-3+3=0+3\\x=3

Therefore, the answer is x=3.
