Question 1032821: place the following quadratic in vertex form by completting the square and then state the coordinates of its vertex.
y=3x^2+24x+43 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! y=3x^2+24x+43
y=3(x^2+8x+43/3)
complete the square
y=3(x^2+8x+16)+43-48,because I added 16 to the parentheses and multiplied that by 3, the coefficient.
y=3(x+4)^2-5
The vertex is at (-4, -5)
