Solution for 2.666666666666666y-(926100/y)=0 equation:



2.666666666666666y-(926100/y)=0
Domain of the equation: y)!=0
y!=0/1
y!=0
y∈R
We add all the numbers together, and all the variables
2.666666666666666y-(+926100/y)=0
We get rid of parentheses
2.666666666666666y-926100/y=0
We multiply all the terms by the denominator
(2.666666666666666y)*y-926100=0
We add all the numbers together, and all the variables
(+2.666666666666666y)*y-926100=0
We multiply parentheses
2y^2-926100=0
a = 2; b = 0; c = -926100;
Δ = b2-4ac
Δ = 02-4·2·(-926100)
Δ = 7408800
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{7408800}=\sqrt{176400*42}=\sqrt{176400}*\sqrt{42}=420\sqrt{42}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-420\sqrt{42}}{2*2}=\frac{0-420\sqrt{42}}{4} =-\frac{420\sqrt{42}}{4} =-105\sqrt{42} $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+420\sqrt{42}}{2*2}=\frac{0+420\sqrt{42}}{4} =\frac{420\sqrt{42}}{4} =105\sqrt{42} $
