(6 - x)(x + 5) \\ 6(x + 5) - x(x + 5) \\ 6x + 30 -  {x}^{2}  - 5x \\  -  {x}^{2}  + x + 30 \\

 -  {x}^{2}  + x + 30 = 0 \\  -  {x}^{2}  + 6x - 5x + 30 = 0 \\  -  x(x - 6) - 5(x - 6) = 0 \\  - x - 5 = 0 \:  \:  \:  \:  \: \:  \:  \:  x - 6 = 0 \\ \:  \:  \:  \:  \:    - x = 5 \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  x = 6\:  \:  \:  \:  \:  \:  \:  \:  \\ x =  - 5  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:
