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.
