changing a quadratic equation from general form to standard form - video

Solving the quadratic equation for the unknown variable becomes a very simple process if done from the standard form. You also have a general formula for this result:

highlight_green%28x=%28-b%2B-+sqrt%28b%5E2-4ac%29%29%2F%282a%29%29

That is according to ax%5E2%2Bbx%2Bc=0. This is a basic model only. YOUR equation uses variables differently than the basic academic model. YOUR unknown variable is 'a'.
