Answer 1

Please help im so stuck

Answer 2

\(\large\color{black}{ y = -2x^2 - 12x + 1 }\)
\(\large\color{black}{ y = -2(x^2 + 6x) + 1 }\)
\(\large\color{black}{ y = -2(x^2 + 6x+9-9) + 1 }\)
\(\large\color{black}{ y = -2(x^2 + 6x+9) +18+ 1 }\)
\(\large\color{black}{ y = -2(x+3)^2 +19 }\)

Answer 3

I made a mistake in my first reply.
