Answer:
[tex] = > x = - 2 \: \: orx = \frac{ - 8}{3} \: [/tex]
Step-by-step explanation:
[tex]3 {x}^{2} + 14x + 16 = 0[/tex]
[tex] = > 3 {x}^{2} + 8x \: + 6x + 16 = 0[/tex]
[tex] = > x(3x + 8) + 2(3x + 8) = 0[/tex]
[tex] = > (x + 2)(3x + 8) = 0[/tex]
[tex] = > x = - 2 \: \: orx = \frac{ - 8}{3} [/tex]
