5x+8/x+12=0
Domain of the equation: x!=0We multiply all the terms by the denominator
x∈R
5x*x+12*x+8=0
We add all the numbers together, and all the variables
12x+5x*x+8=0
Wy multiply elements
5x^2+12x+8=0
a = 5; b = 12; c = +8;
Δ = b2-4ac
Δ = 122-4·5·8
Δ = -16
Delta is less than zero, so there is no solution for the equation
