Match the graph with the number of real solutions.

Zero real soultions

One real solution

Two real solutions

Find the roots shown by the graph

x=-25

No solutions

x={-5, 5}

x={-8, 8}

The zero product property states

If ab=0, then a=0 or b=0.

If ab=-1, then a=-1 or b=-1.

If ab=0, then a=1 or b=1.

If ab=1, then a=1 or b=1.

Which shows the correct use of the zero product property?

Which correctly shows the quadratic formula?

What is the discriminant?

The way to find what the roots are.

Another name for the solutions.

Match the value of the discriminant with the number and type of roots.

Discriminant =0

Discriminant <0

Discriminant >0

0 real roots

1 real root

2 real roots

When completing the quardratic formula, you get a positive prime number as a radicand.  This means that 

you will not have a solution.

you will have exactly one solution.

you could easily graph the parabola to find the solution.

you have an irrational answer as a solution.

Given the quadratic function

identify a, b, and c.

a=3, b=0, c=20

a=3, b=0, c=-20

a=3, b=1, c=-20

a=3, b=1, c=20

Which shows the appropriate way to "branch" the final answer to the quadratic formula?
