Solving Quadratic Equations Test

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

• Copy off neighbor

• Plug into calculator

• Solutions are where the quadratic crosses the x axis

• Magic 8 Ball

What are the x- intercepts?

• (0,0) and (0,4)

• (0,0) and (4,0)

• y= 0

• x= 2

Use the graph to determine the solutions.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

Solve by factoring: 5x² + 13x + 6 = 0

• x = -2 and x = -3/5
• x = 2 and x = 3/5
• x = -2 and x = 3/5
• x = 2 and x = -3/5
