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

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

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

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

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

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

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

Solving
-3 + -1n + 2n2 = 0

Solving for variable 'n'.
