3-x-1+2=13/x-1
We move all terms to the left:
3-x-1+2-(13/x-1)=0
Domain of the equation: x-1)!=0We add all the numbers together, and all the variables
x∈R
-1x-(13/x-1)+4=0
We get rid of parentheses
-1x-13/x+1+4=0
We multiply all the terms by the denominator
-1x*x+1*x+4*x-13=0
We add all the numbers together, and all the variables
5x-1x*x-13=0
Wy multiply elements
-1x^2+5x-13=0
a = -1; b = 5; c = -13;
Δ = b2-4ac
Δ = 52-4·(-1)·(-13)
Δ = -27
Delta is less than zero, so there is no solution for the equation
