20-4x-18/x+2x-7=0
Domain of the equation: x!=0We add all the numbers together, and all the variables
x∈R
-2x-18/x+13=0
We multiply all the terms by the denominator
-2x*x+13*x-18=0
We add all the numbers together, and all the variables
13x-2x*x-18=0
Wy multiply elements
-2x^2+13x-18=0
a = -2; b = 13; c = -18;
Δ = b2-4ac
Δ = 132-4·(-2)·(-18)
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{25}=5$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(13)-5}{2*-2}=\frac{-18}{-4} =4+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(13)+5}{2*-2}=\frac{-8}{-4} =+2 $
