Answer 1

Step-by-step explanation:

${x}^{3} - 3 {x}^{2} - 9x - 5 = \: 0\\ or. \: \: - 2 {x}^{2} - 9x - 5 = 0 \\ or. \: \: - 2 {x}^{2} - 10x - x - 5 =0 \\ or. \: \: - 2x(x+5) - 1(x + 5) = 0 \\ or. \: \: (x + 5)( - 2x - 1) = 0 \\ or. \: \: x + 5 = 0 \: \: \: \: \: | - 2x - 1 = 0 \\ or. \: \: x = - 5 \: \: | \: \: - 2x = 1 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: | or. \: x = \frac{1}{2}$
