Svn=2n^2-n

Solution for Svn=2n^2-n equation:

Simplifying
Svn = 2n2 + -1n

Reorder the terms:
nvS = -1n + 2n2

Solving
nvS = -1n + 2n2

Solving for variable 'n'.

Reorder the terms:
n + nvS + -2n2 = -1n + 2n2 + n + -2n2

Reorder the terms:
n + nvS + -2n2 = -1n + n + 2n2 + -2n2

Combine like terms: -1n + n = 0
n + nvS + -2n2 = 0 + 2n2 + -2n2
n + nvS + -2n2 = 2n2 + -2n2

Solving
1 + -2n + vS = 0

Move all terms containing n to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -2n + -1 + vS = 0 + -1

Reorder the terms:
1 + -1 + -2n + vS = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2n + vS = 0 + -1
-2n + vS = 0 + -1

Combine like terms: 0 + -1 = -1
-2n + vS = -1

Add '-1vS' to each side of the equation.
-2n + vS + -1vS = -1 + -1vS

Combine like terms: vS + -1vS = 0
-2n + 0 = -1 + -1vS
-2n = -1 + -1vS

Divide each side by '-2'.
n = 0.5 + 0.5vS

Simplifying
n = 0.5 + 0.5vS
Solution
n = {0, 0.5 + 0.5vS}
