Solve y=-0.060x^2+1.720x^2-16.398x

$$y = - 0.060 x ^ { 2 } + 1.720 x ^ { 2 } - 16.398 x$$

Solve for y

$$y=x\left(\frac{83x}{50}-16.398\right)$$

Solution Steps

Combine -0.06x^{2} and 1.72x^{2} to get 1.66x^{2}.

$$y=1.66x^{2}-16.398x$$

Solve for x (complex solution)

$$x=-\frac{25\sqrt{\frac{166y}{25}+268.894404}}{83}+\frac{8199}{1660}$$

$$x=\frac{25\sqrt{\frac{166y}{25}+268.894404}}{83}+\frac{8199}{1660}$$

Solve for x

$$x=-\frac{25\sqrt{\frac{166y}{25}+268.894404}}{83}+\frac{8199}{1660}$$

$$x=\frac{25\sqrt{\frac{166y}{25}+268.894404}}{83}+\frac{8199}{1660}\text{, }y\geq -\frac{67223601}{1660000}$$
