0=(x+6)(x+0)

Solution for 0=(x+6)(x+0) equation:

0=(x+6)(x+0)

We move all terms to the left:

0-((x+6)(x+0))=0

We add all the numbers together, and all the variables

-((x+6)(+x))+0=0

We add all the numbers together, and all the variables

-((x+6)(+x))=0

We multiply parentheses ..

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


We calculate terms in parentheses: -((+x^2+6x)), so:

(+x^2+6x)

We get rid of parentheses

x^2+6x

Back to the equation:

-(x^2+6x)


We get rid of parentheses

-x^2-6x=0

We add all the numbers together, and all the variables

-1x^2-6x=0

a = -1; b = -6; c = 0;
Δ = b2-4ac
Δ = -62-4·(-1)·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*-1}=\frac{0}{-2}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-6)+6}{2*-1}=\frac{12}{-2}
=-6
