(n-3)(2n-1)=0

Solution for (n-3)(2n-1)=0 equation:

Simplifying
(n + -3)(2n + -1) = 0

Reorder the terms:
(-3 + n)(2n + -1) = 0

Reorder the terms:
(-3 + n)(-1 + 2n) = 0

Multiply (-3 + n) * (-1 + 2n)
(-3(-1 + 2n) + n(-1 + 2n)) = 0
((-1 * -3 + 2n * -3) + n(-1 + 2n)) = 0
((3 + -6n) + n(-1 + 2n)) = 0
(3 + -6n + (-1 * n + 2n * n)) = 0
(3 + -6n + (-1n + 2n2)) = 0

Combine like terms: -6n + -1n = -7n
(3 + -7n + 2n2) = 0

Solving
3 + -7n + 2n2 = 0

Solving for variable 'n'.
