Math
This is how I did this: 5x^2+10x=20 <--- I left that out, sorry 5x^2+10x-20=0 5(x^2+2x)-20=0 5(x^2+2x-1+1)-20+5 5(x+1)^2-15=0 So I was thinking that (-1,-15) was the vertex because it is in the form y=a(x-h)^2+k ?? Does this make sense?

Math
When completing the square: 5x^2 + 10x - 20 5 ( x^2 + 2x) -20 = 0 5 ( x + 1)^2 -15 = 0 Did I do that right? If so I have another question. When it's in this form, -15 is the y-coordinate of the vertex and 2 the x coordinate of the vertex? If so isnt the x cooridinate of ...
