Given a graph, how can you find the solutions to a quadratic?

• Copy off neighbor

• Plug into calculator

• Where the graph crosses the x-axis

• Where the graph crosses the y-axis

What are the green dots called?

• roots

• vertex

• solutions

• x intercepts

Identify a, b, and c in: x²−6x+14

• a=3,b=5,c=9

• a=1,b=-6,c=14

• a=1,b=-6,c=-14

• a=1,b=6,c=14

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3
*remember right side should =0

• a = 4, b = -8, c = 3
• a = 4, b =-8, c =-3
• a = 4, b = 8, c = 3
• a = 4, b = 8, c = -3

Choose all that represent the Quadratic Formula.

If the discriminant is positive, then the solution will have

• one real solution

• two real solutions

• no real solutions

• one imaginary solution

The discriminant is
