# Math Help - emergency assistance necessary

1. ## Friendly Assistance necessary.

Hi, I'm trying to assist with math HW. Although I've taken Calc many moons ago, I'm struggling to assist with a problem from a pre-cal class, although the question isn't very relevant to calc. I'm not sure what its asking, or how to solve it. A breakdown would be appreciated.

Sincerely,

Mathmom!

$y_0=a(-h)^2+b(-h)+c$

You can also get $y_1$ and $y_2$ in the same way.

Substitute expressions in terms of a,b,c and h for $y_0$, $y_1$ and $y_2$ into the second area formula and you will get the first area formula.
