Best ResponseYou've already chosen the best response.1the vertex is at (5,2) i believe

Best ResponseYou've already chosen the best response.1teh equation tells us the vertex = (5,2) the distance from vertex to focus or directix = 1/4 the focus is at (5,1' 3/4) the parabola opens upwards

Best ResponseYou've already chosen the best response.0everyone keeps telling me to complete the squares, but i don't even know how to do that. i am horrible at math.

Best ResponseYou've already chosen the best response.1complete the square is a process used to make a square complete....add the missing parts really.

Best ResponseYou've already chosen the best response.1A complete square can move freely back and forth between to forms; (x+3)^2 = x^2 +6x +9 ^^^^^^^^ this is a complete square

Best ResponseYou've already chosen the best response.1if all we had was: x^2 +6x. then the square is missing a part to it and it is stuck in this form...

Best ResponseYou've already chosen the best response.1How the incomplete square is made tells us alot about the missing parts

Best ResponseYou've already chosen the best response.1in short, we need to take the number that is next to the 'x'.. that 6 there in this case; and split it in half

Best ResponseYou've already chosen the best response.16/2 = 3 the missing part that we need is then 3^2 x^2 +6x +3^2 = (x+3)^2

Best ResponseYou've already chosen the best response.1the focus and directix are geometry terms used to define a parabola; and any conic section really. It relies upon the geometric interpretation instead of the algebraic

Best ResponseYou've already chosen the best response.1a parabola is: all poionts that are equi distant from a straight line from the focus and a perpendicular line to the directix.
