2x+4/3x=380
We move all terms to the left:
2x+4/3x-(380)=0
Domain of the equation: 3x!=0We multiply all the terms by the denominator
x!=0/3
x!=0
x∈R
2x*3x-380*3x+4=0
Wy multiply elements
6x^2-1140x+4=0
a = 6; b = -1140; c = +4;
Δ = b2-4ac
Δ = -11402-4·6·4
Δ = 1299504
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{1299504}=\sqrt{16*81219}=\sqrt{16}*\sqrt{81219}=4\sqrt{81219}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1140)-4\sqrt{81219}}{2*6}=\frac{1140-4\sqrt{81219}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1140)+4\sqrt{81219}}{2*6}=\frac{1140+4\sqrt{81219}}{12} $
