j-6=1/2*+3
We move all terms to the left:
j-6-(1/2*+3)=0
We get rid of parentheses
j-6-3-1/2*=0
We multiply all the terms by the denominator
j*2*-1-6*2*-3*2*=0
We add all the numbers together, and all the variables
j*2*=0
Wy multiply elements
2j^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
