Talk:Quadratic equation

I don't know correct english terminology, but I think the OP confuses Quadratic equation with Quadratic function. Leopeo 16:00, 10 November 2007 (EST)

Yes, the quadratic equation is ax^2 + bx + c = 0. The quadratic function is y = ax^2 + bx + c or f(x) = ax^2 + bx + c. I think the article has blended the two a little TheGuy 17:31, 10 November 2007 (EST)

In high school, I used to do these all the time. When I look at them today, I don't know where to start on paper. However, when I became a business owner, I found I was doing them all the time in my head, even when I was talking with other people. RobS^{Recovering Republican} 15:50, January 1, 2026 (EST)
