Answer:

\huge{\boxed{\boxed{\sf{x=\frac{30+35\sqrt{23}}{6}\:and\:\frac{30-35\sqrt{23}}{6}}}}}

Step-by-step explanation:

\huge{\boxed{\boxed{\underline{\sf{SOLUTION-}}}}}

Quadratic formula:

3 {x}^{2}  - 30x - 29 = 0 \\ d =  {b}^{2}  - 4ac \\ d =  ({ - 30})^{2}  - 4(3  \times  - 29) \\ d = 900 - 4( - 87) \\  d = 900 + 348 \\ d = 1248 \\  \\ x =  \frac{ - b +  -  \sqrt{d} }{2a}  \\ x =  \frac{ - ( - 30) +   \sqrt{1248} }{2 \times 3}  \\ x =  \frac{30 + 35 \sqrt{23} }{6}  -  -  -  -  - 1st \: zeroes \\ similarly \\ x =  \frac{30 - 35 \sqrt{23} }{6}  -  -  -  -  - 2nd \: zeroes

\huge{\boxed{\boxed{\sf{x=\frac{30+35\sqrt{23}}{6}\:and\:\frac{30-35\sqrt{23}}{6}}}}}
