Hi,
Could someone explain how you work through this kind of sums:
"A parabola has x-axis intercepts 6 and -3 and passes through the point (1, 10). Find the equation of the Parabola"
Any help would be much appreciated,
Thanks,
Dru

You have the following points (1,10),(-3,0) & (6,0)
Use the general form $\displaystyle y= a(x-h)^2+k$ and sub these points in, then solve for a,h and k.
Here's a start
(1,10): $\displaystyle 10= a(1-h)^2+k$
(-3,0): $\displaystyle 0= a(-3-h)^2+k$
(6,0): $\displaystyle 0= a(6-h)^2+k$
