Question 448493
That is the loveliest math expression I have seen in a long time. 
Since it is not an equation I can only guess what you want to do with it.
Only equations have solutions.
Perhaps you want to factor it.
Factor out 3x
3x*(2x^2-x-10)
2*-10=-20
Find factors of -20 which add up to -1
-5 and 4
2x^2+4x-5x-10
2x*(x+2)-5(x+2)
(2x-5)*(x+2)
3x*(2x-5)*(x+2)
