-2x^2+10x+3=0

What is the factored version of this??
Answered by Steve
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.

When I did it I got x=5+-[19] over by 2
Answered by Steve
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.
