3v*3v=v+10

Solution for 3v*3v=v+10 equation:

3v*3v=v+10

We move all terms to the left:

3v*3v-(v+10)=0

Wy multiply elements

9v^2-(v+10)=0

We get rid of parentheses

9v^2-v-10=0

We add all the numbers together, and all the variables

9v^2-1v-10=0

a = 9; b = -1; c = -10;
Δ = b2-4ac
Δ = -12-4·9·(-10)
Δ = 361
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{361}=19$
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-19}{2*9}=\frac{-18}{18}
=-1
$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+19}{2*9}=\frac{20}{18}
=1+1/9
