Try using photomath it works very well
Since 
and 
are roots of 
, we can factorize the quadratic in terms of the roots as
Expanding the right side gives
so that
A polynomial with roots 
and 
would be
and expanding this gives
Now,
and
So we can write the second quadratic in terms of 
as
and to make things look cleaner, scale the whole expression by 
to get
