2/4w-1/2w-4=12
We move all terms to the left:
2/4w-1/2w-4-(12)=0
Domain of the equation: 4w!=0
w!=0/4
w!=0
w∈R
Domain of the equation: 2w!=0We add all the numbers together, and all the variables
w!=0/2
w!=0
w∈R
2/4w-1/2w-16=0
We calculate fractions
4w/8w^2+(-4w)/8w^2-16=0
We multiply all the terms by the denominator
4w+(-4w)-16*8w^2=0
Wy multiply elements
-128w^2+4w+(-4w)=0
We get rid of parentheses
-128w^2+4w-4w=0
We add all the numbers together, and all the variables
-128w^2=0
a = -128; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-128)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$w=\frac{-b}{2a}=\frac{0}{-256}=0$
