Question about Quadric Equations

How about if you change the signs....? Will the zeros be the same? How does the parabola change?

\(\displaystyle x^2+5x+6=0\) and \(\displaystyle -x^2-5x-6=0\)

It is possible to have different quadratic functions with same x-intercepts.

\(\displaystyle f(x) \, = \, A\cdot (x \, - \, p)\cdot (x \, - \, q) \(\displaystyle

Now you can change the value of "A" - to change the shape of the parabola - but the 'x-intercepts' will remain same.

Notice the 'y' intercepts will change with the value of 'A'.

So when you have quadratic equation [f(x)=0], "A" is divided out and it reduces to same equation every time.\)\)
