if 2+sqrt3 is a root then 2-sqrt3 is also root, so sum of roots is 4=-b/a
|dw:1336638007963:dw|
when roots are irrational, they occur as conjugate surds --> that means if one root of the quadratic is 2+sqrt3, the other would be 2-sqrt3. Hence, you can find out product of roots, which is 'q'. and sum of roots which is '-p'.
