Find the discriminant of $$$3 x^{2} - 4 x + 5 = 0$$$.
Solution
The discriminant of the quadratic equation $$$a x^{2} + b x + c$$$ is $$$D = b^{2} - 4 a c$$$.
Our equation is $$$3 x^{2} - 4 x + 5 = 0$$$, so $$$a = 3$$$, $$$b = -4$$$, $$$c = 5$$$.
Thus, $$$D = \left(-4\right)^{2} - \left(4\right)\cdot \left(3\right)\cdot \left(5\right) = -44$$$.
