6x+(-5x)-33*15x^2=0

Wy multiply elements

-495x^2+6x+(-5x)=0

We get rid of parentheses

-495x^2+6x-5x=0

We add all the numbers together, and all the variables

-495x^2+x=0

a = -495; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-495)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-495}=\frac{-2}{-990}
=1/495
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-495}=\frac{0}{-990}
=0
