2r+3/3r-6=6
We move all terms to the left:
2r+3/3r-6-(6)=0
Domain of the equation: 3r!=0We add all the numbers together, and all the variables
r!=0/3
r!=0
r∈R
2r+3/3r-12=0
We multiply all the terms by the denominator
2r*3r-12*3r+3=0
Wy multiply elements
6r^2-36r+3=0
a = 6; b = -36; c = +3;
Δ = b2-4ac
Δ = -362-4·6·3
Δ = 1224
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{1224}=\sqrt{36*34}=\sqrt{36}*\sqrt{34}=6\sqrt{34}$$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-36)-6\sqrt{34}}{2*6}=\frac{36-6\sqrt{34}}{12} $$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-36)+6\sqrt{34}}{2*6}=\frac{36+6\sqrt{34}}{12} $
