SOLUTION:-
8000= (92000-120X^2)/X
= 92000-120X^2 = 8000x
= 12x^2+800x-9200 =0
= 3x^2 + 200x - 2300 =0
= by -b(+-)(b^2-4ac)^1/2)/2a
= {-200(+-)([200)2-4×3×(-2300)]^1/2}/6
= {-200(+-) [40000+27,600]^1/2}/6
= -200(+-) [67,600]^1/2}/6
=( -200(+-)260)/6
x=( -100+130 )/3, x= (-100-130)/3
x= 30/3 , x = -230/3
[x= 10 , x = -230/3]ans
8000= (92000-120X^2)/X
= 92000-120X^2 = 8000x
= 12x^2+800x-9200 =0

[x= 10 , x = -230/3]ans
