Quadratic Formula

Make a true statement about about Graph A

The discriminant is ​ (a)  

There will be ​ (b)  

• zero

• one real solution

• positive

• negative

• two complex solutions

• two real solutions

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

• Positive

• Negative

• Zero

• Not Sure

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

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

• Positive

• Negative

• Zero

• Not Sure

What is this formula?

• This is the speed of light formula.

• This is the quadratic formula.

• This is the zero product property.

• This is scary.

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12

• No Real Solution

Find the roots using the quadratic formula.

• A

• B

• C

• D

If the discriminant is positive, then the quadratic has:

• Real Solution

• Real Solutions

• Half a Solution

• Imaginary Solution

Use the quadratic formula to solve 2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

Solve using the quadratic formula...
