What are the 3 methods for solving quadratic equations?
What are the 3 methods for solving quadratic equations?
Factoring
Quadratic Formula
Completing the Square
5i2 * 2 =
5i2 * 2 = -10
x2 - 12x + 32
Solve on the board by factoring
x2 - 12x + 32
(x - 8)(x - 4)
x = 4, 8

Based on the question, how do you know if you do this:
(x + 5)2 - 21
Or this:
(x + 5)2 = 21
x + 5 = +/- sqrt(21)
x = -5 +/- sqrt(21)
(x + 5)2 - 21: use this when the question says to write in vertex form.
(x + 5)2 = 21
x + 5 = +/- sqrt(21)
x = -5 +/- sqrt(21)
Use this when the question says Solve
4i3 =
4i3 = -4i
x2 + 2x + 12 = 0
Solve on the board using the quadratic formula.
x2 + 2x + 12 = 0
x = -1 +/- sqrt(11)i

(4 + i)(2 - 3i) =
(4 + i)(2 - 3i) = 11 - 10i
x2 + 6x = -12
Solve on the board by completing the square.
x2 + 6x = -12
x = -3 +/- sqrt(3)i

(4+i)(2-3i)(4i+2)(5i-1) =
(4+i)(2-3i)(4i+2)(5i-1) = -182 + 286i
4x2 + 8x + 32 = 0
Solve on the board by completing the square
4x2 + 8x + 32 = 0
x = -1 +/- sqrt(7)i
