15x^2+-3x=0
We add all the numbers together, and all the variables
15x^2-3x=0
a = 15; b = -3; c = 0;
Δ = b2-4ac
Δ = -32-4·15·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-3)-3}{2*15}=\frac{0}{30} =0 $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+3}{2*15}=\frac{6}{30} =1/5 $
