0=0.04x^2+64-3x+164
We move all terms to the left:
0-(0.04x^2+64-3x+164)=0
We add all the numbers together, and all the variables
-(0.04x^2+64-3x+164)=0
We get rid of parentheses
-0.04x^2+3x-64-164=0
We add all the numbers together, and all the variables
-0.04x^2+3x-228=0
a = -0.04; b = 3; c = -228;
Δ = b2-4ac
Δ = 32-4·(-0.04)·(-228)
Δ = -27.48
Delta is less than zero, so there is no solution for the equation
