(11v-12)(12+11v)=0

Solution for (11v-12)(12+11v)=0 equation:

(11v-12)(12+11v)=0

We add all the numbers together, and all the variables

(11v-12)(11v+12)=0

We use the square of the difference formula

121v^2-144=0

a = 121; b = 0; c = -144;
Δ = b2-4ac
Δ = 02-4·121·(-144)
Δ = 69696
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{69696}=264$
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-264}{2*121}=\frac{-264}{242}
=-1+1/11
$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+264}{2*121}=\frac{264}{242}
=1+1/11
