First, let's combine all like terms. 

By setting up a quadratic, we get \(3x^{2}+4x+10\)

 

The descriminant of a quadratic can be written in the form \(b^2-4ac\) for quadratcis written in the form \(ax^2+bx+c\)

 

Thus, we have

\(4^2-4(3)(10)\\ 16-120\\ -104\)

 

So -104 is our answer

 

Thanks! :)
