1.
[tex] {x}^{2} - x - 12 \\ {x}^{2} - 4x + 3x - 12 \\ x(x - 4) + 3(x - 4) \\ (x - 4)(x + 3) \\ [/tex]
so the zeros of this polynomial are
[tex]x = 4 \: and \: x = - 3[/tex]
2.
[tex] {x}^{2} - 6x + 9 \\ {x}^{2} - 3x - 3x + 9 \\ x(x - 3) - 3(x - 3) \\ (x - 3)(x - 3) [/tex]
so the zeros of this polynomial are
x=3
