x*x+8/9=2x
We move all terms to the left:
x*x+8/9-(2x)=0
We add all the numbers together, and all the variables
-2x+x*x+8/9=0
Wy multiply elements
x^2-2x+8/9=0
We multiply all the terms by the denominator
x^2*9-2x*9+8=0
Wy multiply elements
9x^2-18x+8=0
a = 9; b = -18; c = +8;
Δ = b2-4ac
Δ = -182-4·9·8
Δ = 36
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{36}=6$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-6}{2*9}=\frac{12}{18} =2/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+6}{2*9}=\frac{24}{18} =1+1/3 $
