Is what equal to zero, on the right side of equation? Also, a parabola can be any narrowness or wide, so no you can't solve this. Any value for a is valid. Oh wait, you have set y = 0, haven't you? Oh, so there is a solution perhaps. But you need to know where you want the parabola to pass through the x-axis. If you know the roots of the equation or the points on the x-axis, then you can calculate the "a" number.]]>http://www.mathisfunforum.com/profile.php?id=11082006-05-10T14:36:31Zhttp://www.mathisfunforum.com/viewtopic.php?pid=34600#p34600<![CDATA[Re: Quadratic Help]]>why have you started the third topic with the same question?? keep all the questions in one topic!!!!
