-750x^2+480x-30=250x^2+1002-10x^2
We move all terms to the left:
-750x^2+480x-30-(250x^2+1002-10x^2)=0
We get rid of parentheses
-750x^2-250x^2+10x^2+480x-1002-30=0
We add all the numbers together, and all the variables
-990x^2+480x-1032=0
a = -990; b = 480; c = -1032;
Δ = b2-4ac
Δ = 4802-4·(-990)·(-1032)
Δ = -3856320
Delta is less than zero, so there is no solution for the equation
