1) Either by:
a) Solving the equation, taking the reciprocals of the roots (a and b, say), and forming the quadratic equation
but that's long-winded.
Alternatively note that for a q.e. , if the roots are and , we have:
Divide by to get:
and then note that
So your equation is then:
and then multiply by to get the answer.
Plug in your numbers and you're done.
