0.04-0.2x=x^2+0.09-0.6x
We move all terms to the left:
0.04-0.2x-(x^2+0.09-0.6x)=0
We get rid of parentheses
-x^2-0.2x+0.6x-0.09+0.04=0
We add all the numbers together, and all the variables
-1x^2+0.4x-0.05=0
a = -1; b = 0.4; c = -0.05;
Δ = b2-4ac
Δ = 0.42-4·(-1)·(-0.05)
Δ = -0.04
Delta is less than zero, so there is no solution for the equation
