Final answer:

To find y by implicit differentiation for the equation 4x² + 3y² = 6, differentiate both sides with respect to x. Use the power rule for differentiation and the chain rule for the y term. Isolate dy/dx to obtain the final result.

Step-by-step explanation:

To find y by implicit differentiation for the equation 4x² + 3y² = 6, we need to differentiate both sides of the equation with respect to x.

  1. For the left side of the equation, we apply the power rule for differentiation, which states that if we have a term of the form ax^n, its derivative is given by d/dx(ax^n) = nax^(n-1). So, the derivative of 4x² would be 8x.
  2. For the right side of the equation, we differentiate the constant term, which is 6, resulting in 0.
  3. For the term 3y², we apply the chain rule. The derivative of y² with respect to x would be 2y * (dy/dx) by the chain rule.

So, applying the above steps, we get:

8x + 2y * (dy/dx) = 0

To find dy/dx, we isolate it by moving the 8x term to the other side:

dy/dx = -8x / (2y)

Simplifying further, we get:

dy/dx = -4x / y
