(2/x+1)+3x=4
We move all terms to the left:
(2/x+1)+3x-(4)=0
Domain of the equation: x+1)!=0We add all the numbers together, and all the variables
x∈R
3x+(2/x+1)-4=0
We get rid of parentheses
3x+2/x+1-4=0
We multiply all the terms by the denominator
3x*x+1*x-4*x+2=0
We add all the numbers together, and all the variables
-3x+3x*x+2=0
Wy multiply elements
3x^2-3x+2=0
a = 3; b = -3; c = +2;
Δ = b2-4ac
Δ = -32-4·3·2
Δ = -15
Delta is less than zero, so there is no solution for the equation
