n2-n=88

Solution for n2-n=88 equation:

n2-n=88

We move all terms to the left:

n2-n-(88)=0

We add all the numbers together, and all the variables

n^2-1n-88=0

a = 1; b = -1; c = -88;
Δ = b2-4ac
Δ = -12-4·1·(-88)
Δ = 353
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-\sqrt{353}}{2*1}=\frac{1-\sqrt{353}}{2}
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{353}}{2*1}=\frac{1+\sqrt{353}}{2}
