 \mathsf {x = ( 3) \: and  \:   -2}

Explicação passo-a-passo:

 {x}^{2}  +  - x - 6 = 0 \\  {x}^{2}  - 3x + 2x - 6 = 0 \\ x(x - 3) + 2(x - 3) = 0 \\ (x - 3)(x + 2) = 0 \\   \red{\mathsf{x = 3 \: and \:  (- 2)}}

Explicação passo-a-passo:

x ^{2}  - x - 6 \\  =  >  {x}^{2}  - 3x + 2x - 6 \\  =  > x(x - 3) + 2(x - 3) \\  =  > (x + 2)(x - 3) \\ i.e.  \: x = ( - 2) \: and(3)
