anonymous · Answer

I'll just briefly go over it. 
Discriminant of quadratic is define by b^2-4ac
if the D is greater than zero than the quadratic will have to 2 real roots, if the D is equal to zero then you will have 2 of the same roots, and D is less than zero there are no real roots.

the idea behind the exercises is to go over material already cover
I mean..... is not like your teacher will start chapter 5 say, by going to page 50 and then back to page 40

so the chapter or sections have to be covered for the exercise being assigned
