Quadratic Formula Fun

The quadratic equation can be used to solve quadratic equations that cannot be factored.

• True
• False

Identify the values of A, B, and C

3m² - 14 = 11m

• A=3, B=-11, C=-14

• A=3, B=-14, C=11

• A=3, B=11, C=-14

• A=3, B=-14, C=11

The discriminant is

• aX²  + bX  +  c
• b - 4ac
• b² - 4ac
• b² + 4ac

If the discriminant equals 0, then the quadratic has:

• 1 Rational Solution

• 2 Rational Solutions

• No solutions

• 2 Complex Solutions

If the discriminant is positive but NOT a perfect square, then the quadratic has:

• 1 Rational Solution

• 2 Irrational Solutions

• 2 Rational Solutions

• 2 Complex Solutions

If the discriminant is negative, then the quadratic has:

• 1 Rational Solution

• 2 Rational Solutions

• 2 Irrational Solutions

• 2 Complex Solutions

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6
• x = -5/2, x =5
• x = -3/7, x =6
• x = -5/2, x = 7
