Homework Statement
Given that the equation [tex] x^{3} + ax^{2} + bx + c = 0 [/tex] has the roots [tex]r_{1}, r_{2}, r_{3}[/tex], develop formulae for [tex]r_{1} + r_{2} + r_{3}, r_{1}r_{2}+r_{1}r_{3}+r_{2}r_{3}, r_{1}r_{2}r_{3} [/tex]
Homework Equations
The Attempt at a Solution
Not really sure where to attempt to start this problem. Only thing I know is that the roots of the equation imply
[tex](x-r_{1})(x-r_{2})(x-r_{3})=0[/tex]
