If you mean
6x^2-x+3 < 5x^2+5x-5
then just collect terms on one side, and you get
x^2-6x+8 < 0
(x-2)(x-4) < 0
This is a parabola which opens upward, so it is negative between the roots. Thus
2 < x < 4
A product is negative if exactly one of the factors is negative.
solve quadiratic inequalitiy using product propertise
6xsq -x+3<5xsq+5x-5
