Answer:

I'mnot sure if you're asking for its roots..but here you go :)

Step-by-step explanation:

= 6 {x}^{2} + 19 + 9 {x}^{2}   - 8 \\  = (6 {x}^{2}  + 9 {x}^{2} ) + (19 - 8) \\  = 15 {x}^{2}  + 8 \\ 15 {x}^{2}  =  - 8 \\  {x}^{2}  =   - \frac{8}{15} \\  \sqrt{ {x}^{2} }  =  \sqrt{  - \frac{8}{15} }   \\ x =  \sqrt{ \frac{8}{15}}  \times  \sqrt{ - 1}  \\ x =  \sqrt{ \frac{8}{15} }  \times i \\  x1 = 0.7302i \\ x2 =  - 0.7302i
