Solution for 2n^2(n-3)-4(n-3)=(n-3) equation: 


Simplifying
2n2(n + -3) + -4(n + -3) = (n + -3)

Reorder the terms:
2n2(-3 + n) + -4(n + -3) = (n + -3)
(-3 * 2n2 + n * 2n2) + -4(n + -3) = (n + -3)
(-6n2 + 2n3) + -4(n + -3) = (n + -3)

Reorder the terms:
-6n2 + 2n3 + -4(-3 + n) = (n + -3)
-6n2 + 2n3 + (-3 * -4 + n * -4) = (n + -3)
-6n2 + 2n3 + (12 + -4n) = (n + -3)

Reorder the terms:
12 + -4n + -6n2 + 2n3 = (n + -3)

Reorder the terms:
12 + -4n + -6n2 + 2n3 = (-3 + n)

Remove parenthesis around (-3 + n)
12 + -4n + -6n2 + 2n3 = -3 + n

Solving
12 + -4n + -6n2 + 2n3 = -3 + n

Solving for variable 'n'.

Reorder the terms:
