100
a u shape
How does a parabola look like?
200
24(x + 2y)

200
It tells you how many real solutions or real roots a quadratic has.
What is the purpose of the discriminant?
200
postive
If it is a>0 is it postive or negative?
300
(8r 2 + 1) (r-8)

You can work backwards
What do you think we can do next to finish factoring these problems?
500
the discriminant you fing how many real solution are there and the quadratic equation tou find the solutions.
What is the difference between finding the discriminant and solving the quadractic equation?
