((-1)/2)=B
We move all terms to the left:
((-1)/2)-(B)=0
We add all the numbers together, and all the variables
-1B+((-1)/2)=0
We multiply all the terms by the denominator
-1B*2)+((-1)=0
Wy multiply elements
-2B^2=0
a = -2; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-2)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$B=\frac{-b}{2a}=\frac{0}{-4}=0$
