Having a bit of trouble with this one. Can anyone help?

Many thanks.The roots of the equation are & . Show that .

Q.: (i)(ii)The roots of are & . Find the value of p & the value of q.

Attempt: (i)a = 2, b = 6, c = 3

=> => -3

=>

Sum of roots: => => => => 9 - 3 => 6

(ii)a = 2, b = p, c = q

Sum of roots: => => => => => => =>

Product of roots: => => => => => => => =>

(sum of roots)x + (product of roots) => => ...

Ans.:(From text book): p = 18, q = 39
