Step-by-step explanation:

We have,

3 {x}^{2}  + 11x + 10 > 0

 \implies3 {x}^{2}  + 5x  + 6x+ 10 > 0

 \implies \: x(3 x  + 5) + 2(3x+ 5) > 0 \\

 \implies \: (x + 2)(3 x  + 5)  > 0 \\

 \implies \: 3(x + 2) \left( x  +  \dfrac{5}{3} \right)  > 0 \\

 \implies \: (x + 2) \left( x  +  \dfrac{5}{3} \right)  > 0 \\

 \implies x \in \left(  -  \infty , - 2\right)  \cup \left( - \dfrac{5}{3}  , \infty \right)\\
