Solution for m2-6=-m equation:

m2-6=-m

We move all terms to the left:

m2-6-(-m)=0

We add all the numbers together, and all the variables

m2-(-1m)-6=0

We add all the numbers together, and all the variables

m^2-(-1m)-6=0

We get rid of parentheses

m^2+1m-6=0

We add all the numbers together, and all the variables

a = 1; b = 1; c = -6;
Δ = b2-4ac
Δ = 12-4·1·(-6)
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-5}{2*1}=\frac{-6}{2}
=-3
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+5}{2*1}=\frac{4}{2}
=2
