SOLUTION

Step1: Write out the equation


y=-2x^2-4x+2

Compare the equation with the general form of a quadratic equation


\begin{gathered} y=ax^2+bx+c \\ \text{then } \\ a=-2,b=-4,c=2 \end{gathered}

Step2 Write out the quadratic formula


x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

Step3: Substitute the parameters in step1
