2x+5/x-4=0
Domain of the equation: x!=0We multiply all the terms by the denominator
x∈R
2x*x-4*x+5=0
We add all the numbers together, and all the variables
-4x+2x*x+5=0
Wy multiply elements
2x^2-4x+5=0
a = 2; b = -4; c = +5;
Δ = b2-4ac
Δ = -42-4·2·5
Δ = -24
Delta is less than zero, so there is no solution for the equation
