+661 Find the discriminant of the quadratic 5x^2 - 2x + 8 - 2x^2 + 6x + 2.
+1786 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! :)
