Answer:
1.
[tex]x = - 5 \: or \: x = 3 \: or \: x = 1[/tex]
2.
[tex]x = 3[/tex]
Step-by-step explanation:
1.
[tex](x + 5)(x - 3)(x - 1) = 0 \\ x + 5 = 0 \: or \: x - 3 = 0 \: or \: x - 1 = 0 \\ answer \: \: \: x = - 5 \: or \: x = 3 \: or \: x = 1[/tex]
2.
[tex]x \times 3 + 2x \times 2 - 5x - 6 = 0 \\ 3x + 4x - 5x - 6 = 0 \\ 2x - 6 = 0 \\ 2x = 6 \\ x = \frac{6}{2} \\ x= 3[/tex]
