Tuesday
Learning Target: I can use complex numbers to factor a sum of squares.
Factoring a difference of squares always results in (x + a)(x - a) *Sometimes there are additional coefficients!*
Factoring a sum of squares is only possible with complex numbers. Create a difference of squares using the imaginary unit, i. (x + ai)(x - ai) Factor out the GCF first!

Multiple Choice
Factor the difference of squares:
x2−36
(x+6)(x+6)
(x+36)(x−1)
(x−6)(x−6)
(x+6)(x−6)
4
Multiple Choice
Factor the sum of squares:
x2+36
(x+6)(x−6)
(x+6i)(x−6i)
(6x+1)(x+36)
(x+i)(x−i)

Wednesday
Learning Target: I can solve a quadratic equation with complex solutions.
Factor the quadratic equation and solve for the value of x from both factors that will make the equation equal to 0.
There will always be 2 values of x as your answer!
6
Multiple Choice
Solve the quadratic equation for x:
x2−36=0
x=6
x=−6
x=±6
x=6i
7
Multiple Choice
Solve the quadratic equation for x:
x2+36=0
x=6
x=−6
x=±6
x=±6i
