Sum of roots taken one at a time is -b/a
Sum of roots taken two at a time is c/a
three at a time is -d/a
four at a time is e/a
The Attempt at a Solution
I did part one by solving the two equations simultaneously.
For part two, I said that it has those roots because that is where the two curves touch
I'm stuck on part three - tried to solve it by applying the above equations and eliminating [itex]\gamma[/itex] and [itex]\delta[/itex] since they are equal to [itex]\alpha[/itex] and [itex]\beta[/itex] respectively but this did not work.
Help would be greatly appreciated :)
