0=-0.12x^2=3x
We move all terms to the left:
0-(-0.12x^2)=0
We add all the numbers together, and all the variables
-(-0.12x^2)=0
We get rid of parentheses
0.12x^2=0
a = 0.12; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·0.12·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$x=\frac{-b}{2a}=\frac{0}{0.24}=0$
