It does not factor over the rationals, since the discriminant
b^2-4ac = 100+24 = 124
is not a perfect square. Use the quadratic formula to find the roots, or maybe there's a typo.
-2x^2+10x+3=0
What is the factored version of this??

When I did it I got x=5+-[19] over by 2
interesting, since 124 = 4*31
Where did you get the 19?
"over by"? Try just "over"
Better yet, use real math
(5+-[31])/2
Though I have never seen [] used to denote square root before.
