Quadratic formula

Eh, what's up doc? Can ya tell me what the discriminant is?

• aX²  + bX  +  c

• b - 4ac

• b² - 4ac

• b² + 4ac

Eh, what's up, doc? For the function above, can ya tell me if the discriminant is positive, negative, or zero?

• Positive

• Negative

• Zero

• Not Sure

Eh, what's up, doc? For the function above, can ya tell me if the discriminant is positive, negative, or zero?

• Positive

• Negative

• Zero

• Not Sure

Eh, what's up doc? Can ya figure out the values of

a, b, and c for

this here 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

Eh, what's up doc? Can ya figure out the value of the discriminant and tell me about the number and type of roots for this here equation:

x² + 7x + 13

• 101, 2 real roots

• 3, 2 real roots

• -101, 2 imaginary roots

• -3, 2 imaginary roots

Eh, what's up doc? Can ya use that there quadratic formula to figure out 2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

Eh, what's up doc? Can ya tell me what this formula is?

• Eh, this is the speed of light formula, ain't it doc?

• This is the quadratic formula, ain't it doc?

• This is the zero product property, ain't it doc?

• This is scary, ain't it doc?

Eh, what's up doc? If the discriminant is a negative number, then what's the deal with the quadratic? How many solutions does it have?

• Just 1 real solution, ain't it?

• Or, is it 2 real solutions, doc?

• Maybe, half a solution?

• Or, is it 2 complex (imaginary) solutions, ain't it?

Eh, what's up doc? Can the quadratic equation be used to solve quadratic equations that can or cannot be factored, ain't that right?

• True

• False

Eh, what's up doc? Choose one, will ya?

• A

• B

• C

• D
