Number and Type of Roots, Linear and Quadratic Systems

• Real and distinct

• Repeated

• Complicated

• Complex

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

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

The formula to determine the number of solutions of a quadratic equation is called the discriminant which is...

• aX² + bX + c

• b - 4ac

• b² - 4ac

• b² + 4ac

Which graph shows a quadratic equation that has a discriminant = 0?

• 
• 
• 
• 

For the function below, is the discriminant positive, negative, or zero?

___________

y = x² + 4x + 4

• Positive

• Negative

• Zero
