Step-by-step explanation:

 \frac{3 -  +   \sqrt{19} }{5}

is outcome

given:-

5 {x}^{2}   - 6x - 2 = 0

asked:-

both value of "x"

analysing the question

we get:-

a= 5

b=-6

c-2

because we can't factories this equation normally so we will use this formula :-

x =   \frac{ - b -  +  \sqrt{ {b}^{2} - 4ac } }{2a}

putting those value in the equation:-

x =  \frac{ - ( - 6)  -  +  \sqrt{ ({ - 6)}^{2} - 4 \times 5 \times ( - 2) }  }{2 \times 5}

x =  \frac{6 -  +  \sqrt{36 + 40} }{10}  \\ x =  \frac{6 -  +  \sqrt{76} }{10}

x =  \frac{6 -  + 2 \sqrt{19} }{10}  =  \frac{3 -  +  \sqrt{19} }{5}

this is your answer
