\[y=2x^2-7x+12\]

That equation can be graphed without any converting. Do you need help with graphing an equation?

  • anonymous
No... Turning it into graphing form. it's a different equation.

With H and K, so I can state the vertex.

  • wolf1728
Well that's a new one for me. If you want to state the vertex you can figure it out.
anonymous
  • anonymous
No, It's an actual equation that has the vertex in it.

I just don't know how to go from this equation to that.

Exactly what is this conversion process called? What do they call it when you are being taught this?

Graphing form. She says to convert this quadratic equation into a graphing equation. It has to do with H and K as the vertex points.

That's new to me. Perhaps someone else can help you with this.

I doubt it. Been waiting for a long time. It changes that original equation so it looks like this : y=a(x+h)^2 + k

I'll do some internet surfing for this.

It took me awhile to even remember that form. But it has something to do with completing the square.
wolf1728
  • wolf1728
Yes, I found some sites that discuss this and I do know how to complete the square but I don't think this "vertex graphing" is something I can learn in just a couple of minutes.

It's all good. It took me a whole year to just barely understand it.

Well I'll complete the square 2x² −7x +12 = 0 2x² −7x = -12 x² -3.5x = -6 Taking the coefficient of x which is -3.5 dividing it by 2 then squaring it yields 3.0625 We add this to both sides of the equation x² -3.5x +3.0625 = -6 + 3.0625 Then take the square root of the equation (x + 1.75) (x + 1.75) = Square Root of -2.9375 The equation does not have rational roots and so it will not cross the x axis
