What is the value of the discriminant for the quadratic equation –3 = –x2 + 2x? discriminant = b2 – 4ac –8 4 8 16

The discriminant of a quadratic expression , where a in not 0, is the expression 
                                       .  

We can rewrite  as .

Thus, a=-1, b=2, c=3. Substituting these values in  , we have:

                               .
