14. 2z^2 - 4z + 2 =0
First factor out a 2
2(z^2 - 2z + 1) = 0
Now factor the z^2
2(z - 1)(z - 1)
z = 1 , 1 A
15. x^2 +6x = 0
factor out an x
x(x + 6) = 0
X = 0, -6 B
16.
6x^2 - 17x -14 = 0
Factor
(2x - 7)(3x +2) = 0(use the diamond method so solve this)
x = 7/2 , -2/3 D
17.
Simplify
15x^2 - 14x - 8 = 0 (use the diamond method to factor)
(3x -4)(5x + 2) = 0
x = 4/3, -2/5 B
