-2x(27x-3)=0
We multiply parentheses
-54x^2+6x=0
a = -54; b = 6; c = 0;
Δ = b2-4ac
Δ = 62-4·(-54)·0
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$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-6}{2*-54}=\frac{-12}{-108} =1/9 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+6}{2*-54}=\frac{0}{-108} =0 $
