What's the vertex and how did you get it?

Answers

The

3x^2 + 24x + 36 = 0 \implies 3(x^2 + 8x) + 36 = 0 \implies \n \n 3\left\{x^2 + {\bf 8}x + \left((\bf 8)/(2) \right)^2 - \left((\bf 8)/(2) \right)^2 \right\} + 36 = 0 \implies \n \n 3\left\{x^2 + {\bf 8}x + 16 - 16 \right\} + 36 = 0 \implies \n 3\Big\{(x+4)^2 - 16 \Big\} + 36 = 0 \implies \n \n 3(x+4)^2 - 16(3) + 36 = 0 \implies 3(x+4)^2 - 12 = 0

The vertex is (-4, 12) because a(x - b)^2 + c has vertex (b, c) so 3(x+4)^2 - 12 has vetex (-4, 12)
