Q. Given the function y=2x3+13+x y=\frac{2 x^{3}+1}{3+x} , find dydx \frac{d y}{d x} in simplified form.\newlineAnswer: dydx= \frac{d y}{d x}=
  1. Identify Function: Identify the function that needs to be differentiated.\newlineWe are given the function y=2x3+13+xy=\frac{2x^{3}+1}{3+x}, and we need to find its derivative with respect to xx, which is denoted as dydx\frac{dy}{dx}.
  2. Apply Quotient Rule: Apply the quotient rule for differentiation.\newlineThe quotient rule states that if we have a function y=uvy = \frac{u}{v}, where both uu and vv are functions of xx, then the derivative of yy with respect to xx is given by dydx=vdudxudvdxv2\frac{dy}{dx} = \frac{v\frac{du}{dx} - u\frac{dv}{dx}}{v^2}. Here, u=2x3+1u = 2x^3 + 1 and v=3+xv = 3 + x.
  3. Differentiate uu: Differentiate uu with respect to xx. The derivative of u=2x3+1u = 2x^3 + 1 with respect to xx is dudx=6x2\frac{du}{dx} = 6x^2.
  4. Differentiate vv: Differentiate vv with respect to xx. The derivative of v=3+xv = 3 + x with respect to xx is dvdx=1\frac{dv}{dx} = 1.
  5. Apply Quotient Rule: Apply the quotient rule using the derivatives from steps 33 and 44.\newlineSubstitute the derivatives into the quotient rule formula to get dydx=(3+x)(6x2)(2x3+1)(1)(3+x)2\frac{dy}{dx} = \frac{(3 + x)(6x^2) - (2x^3 + 1)(1)}{(3 + x)^2}.
  6. Simplify Expression: Simplify the expression. Expand the numerator to get (dy)/(dx)=(18x2+6x2)(2x3+1)(dy)/(dx) = (18x^2 + 6x^2) - (2x^3 + 1) and simplify further.
  7. Combine Like Terms: Combine like terms in the numerator.\newlineCombine the terms to get (dydx=24x22x31)(\frac{dy}{dx} = 24x^2 - 2x^3 - 1).
  8. Factor Numerator: Factor the numerator if possible.\newlineIn this case, the numerator cannot be factored in a way that will cancel with the denominator, so we leave the expression as is.
  9. Final Simplified Form: Write the final simplified form of the derivative.\newlineThe final simplified form of the derivative is (dy)/(dx)=(24x22x31)/((3+x)2)(dy)/(dx) = (24x^2 - 2x^3 - 1)/((3 + x)^2).
