3x+261=4x-2/5x+212
We move all terms to the left:
3x+261-(4x-2/5x+212)=0
Domain of the equation: 5x+212)!=0We get rid of parentheses
x∈R
3x-4x+2/5x-212+261=0
We multiply all the terms by the denominator
3x*5x-4x*5x-212*5x+261*5x+2=0
Wy multiply elements
15x^2-20x^2-1060x+1305x+2=0
We add all the numbers together, and all the variables
-5x^2+245x+2=0
a = -5; b = 245; c = +2;
Δ = b2-4ac
Δ = 2452-4·(-5)·2
Δ = 60065
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(245)-\sqrt{60065}}{2*-5}=\frac{-245-\sqrt{60065}}{-10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(245)+\sqrt{60065}}{2*-5}=\frac{-245+\sqrt{60065}}{-10} $
