Question

identify the vertex of y=-2x^2-12x+1

Answer 1

\(\bf \textit{vertex of a parabola}\\ \quad \\
y = {\color{red}{ -2}}x^2{\color{blue}{ -12}}x{\color{green}{ +1}}

\qquad \qquad
\left(-\cfrac{{\color{blue}{ b}}}{2{\color{red}{ a}}}\quad ,\quad {\color{green}{ c}}-\cfrac{{\color{blue}{ b}}^2}{4{\color{red}{ a}}}\right)\)
