88/n=4,n=

Solution for 88/n=4,n= equation:

88/n=4.n=

We move all terms to the left:

88/n-(4.n)=0


Domain of the equation: n!=0

n∈R


We add all the numbers together, and all the variables

88/n-(+4.n)=0

We get rid of parentheses

88/n-4.n=0

We multiply all the terms by the denominator


-(4.n)*n+88=0

We add all the numbers together, and all the variables

-(+4.n)*n+88=0

We multiply parentheses

-4n^2+88=0

a = -4; b = 0; c = +88;
Δ = b2-4ac
Δ = 02-4·(-4)·88
Δ = 1408
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1408}=\sqrt{64*22}=\sqrt{64}*\sqrt{22}=8\sqrt{22}$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{22}}{2*-4}=\frac{0-8\sqrt{22}}{-8}
=-\frac{8\sqrt{22}}{-8}
=-\frac{\sqrt{22}}{-1}
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{22}}{2*-4}=\frac{0+8\sqrt{22}}{-8}
=\frac{8\sqrt{22}}{-8}
=\frac{\sqrt{22}}{-1}
