I assume you are studying implicit differentiation. Solving for dy/dx.
For the Left side use product rule. For Right side, use chain rule. Remember any time you take derivative of "y-term" you must multiply it by dy/dx.

Get dy/dx terms on one side:

Factor out dy/dx and solve:
she Could have wriiten 2(9+1)^2+6+134 did that help!!!!!!!!!??????????
to check maybe u should try it jsut caculate it :D
Answer:
-4y^3 + 4y^2 - 6y + 25
Step-by-step explanation:
<u>Step 1: Distribute the plus</u>
(-4y^3 – 5y +16) + (4y^2 – y + 9)
-4y^3 - 5y + 16 + 4y^2 - y + 9
<u>Step 2: Combine like terms</u>
-4y^3 - 5y + 16 + 4y^2 - y + 9
-4y^3 + 4y^2 - 6y + 25
