5x^2-36x+36=9
We move all terms to the left:
5x^2-36x+36-(9)=0
We add all the numbers together, and all the variables
5x^2-36x+27=0
a = 5; b = -36; c = +27;
Δ = b2-4ac
Δ = -362-4·5·27
Δ = 756
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{756}=\sqrt{36*21}=\sqrt{36}*\sqrt{21}=6\sqrt{21}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-36)-6\sqrt{21}}{2*5}=\frac{36-6\sqrt{21}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-36)+6\sqrt{21}}{2*5}=\frac{36+6\sqrt{21}}{10} $
