Pregunta: y=ln(9x2−4x+1)

Given $\mathrm{y}=\ln (9{\mathrm{x}}^2-4\mathrm{x}+1)$

differentiating with respect to $\mathrm{x}$ and using chain rule we get

$\frac{\mathrm{d}\mathrm{y}}{\mathrm{d}\mathrm{x}}={\mathrm{y}}^{{}^{\prime }}=\frac{\mathrm{d}}{\mathrm{d}\mathrm{x}}\left(\ln (9{\mathrm{x}}^2-4\mathrm{x}+1)\right)$
