$b) \: x _{1} = \frac{3}{2} + \frac{ \sqrt{7} }{2} i, \: x_{2} = \frac{3}{2} - \frac{ \sqrt{7} }{2} i$

$c) \: x_{1} = 1, \: x_{2} = 2$

$d) \: x_{1} = 2, \: x_{2} = 5$

$e) \: x_{1} = 2, \: x_{2} = 3$

$f) \: x_{1} = 2, \: x_{2} = 6$

$g) \: x_{1} = - 4,\: x_{2} = 2$

$h) \: x = 2$

$i) \: x_{1} = - 1, \: x _{2} = 5$

$j) \: x_{1} = - 3, \: x_{2} = 4$

$k) \: x_{1} = 1, \: x_{2} = 5$

$l) \: x = - 3$
