n-1*n=n^2-n

Solution for n-1*n=n^2-n equation:

n-1n=n^2-n

We move all terms to the left:

n-1n-(n^2-n)=0

We add all the numbers together, and all the variables

-(n^2-n)=0

We get rid of parentheses

-n^2+n=0

We add all the numbers together, and all the variables

-1n^2+n=0

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

$\sqrt{\Delta}=\sqrt{1}=1$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-1}=\frac{-2}{-2}
=1
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-1}=\frac{0}{-2}
=0
