Eccentricity of a given ellipse is dependent on how stretched (flattened) it is. A circle is a special case of ellipse but with no eccentricity. If you stretch a circle into an ellipse of greater eccentricity, the foci will get separated along with it. This implies that as the ellipse gets stretched more and more, the foci gets further apart so is the eccentric.
From the above info we can deduce that as the distance between foci decreases, the eccentricity will also reduce.
Given the stated equation we know that that quadratic formula has 2 as its degree. This meats it has 2 roots. A linear equation has a degree of 1. A linear equation has 1 root. To know if they intersect, the must have one root in common. To know this, solve the two equation simultaneously. If they result to an answer then they intersect.
After rearranging the formula to get a on one side you get:
a = (V-T)/b
