10
Write out the discriminant from the Quadratic Formula.
Did you write it correctly? If so then you get the points.
True or False: Imaginary numbers are fun!
True
Factor the following expression:
x2+7x+12
What is:
(x+4)(x+3)
Complete the square and write the equation in vertex form:
y=x2+6x-7
y=(x+3)2-16
Write out the Quadratic Formula
You better have written it correctly or you will have to sing the song in front of class.
If the discriminant is positive what how many and what kind of solutions will you have?
2 real
Simplify: Square Root of -20
2 square root 5 i
Factor the following:
2x2+7x+3
What is:
(2x+1)(x+3)
True or False? It is hip to be square.
True
Huey Lewis and the News said so in the 1980s.
Solve using the Quadratic Formula:
x2-12x+32=0
x=8 or x=4
If the discriminant is negative what kind of solutions will you have?
2 complex solutions like 3 + 4i
What happens if you multiply a complex number by its conjugate?
You will get a real number.
Solve by factoring:
x2-5x+6=0
What is:
x=2 or x=3
Solve by Completing the Square:
x2+8x-9=0
x=1 or x=-9
Solve using the Quadratic Formula
x2+4x+5=0
x=-2+i or x=-2-i
If the discriminant is zero what kind of solutions will you have?
You will have 1 real solution. It means the vertex is on the x axis.
What is 3+2i multiplied by its conjugate?
13
Solve by Factoring:
3x2+11x+6=0
What is:
x=-2/3 or x=-3
Solve by Completing the Square:
x2+6x-7=0
x=1 or x=-7
Your entire team must stand in front of the class and sing the Quadratic Formula Song. Throw in some choreography for extra fun.
Did your team sing the song? If so you get the points.
