-1%283x%5E2%2B10x%2B8%29

10%5E2-4%2A3%2A8=100-4%2A24=100-96=4;
sqrt%284%29=2---- factorizing will work.

-1%2A%283x%2B4%29%28x%2B2%29, DONE.

This could be done well enough using logical trials. Coefficient of 3 depends on factors 1 and 3; constant term would either be some arrangment of 1 and 8, or 2 and 4.
