(4n+3)(n-1)=0

Solution for (4n+3)(n-1)=0 equation:

Simplifying
(4n + 3)(n + -1) = 0

Reorder the terms:
(3 + 4n)(n + -1) = 0

Reorder the terms:
(3 + 4n)(-1 + n) = 0

Multiply (3 + 4n) * (-1 + n)
(3(-1 + n) + 4n * (-1 + n)) = 0
((-1 * 3 + n * 3) + 4n * (-1 + n)) = 0
((-3 + 3n) + 4n * (-1 + n)) = 0
(-3 + 3n + (-1 * 4n + n * 4n)) = 0
(-3 + 3n + (-4n + 4n2)) = 0

Combine like terms: 3n + -4n = -1n
(-3 + -1n + 4n2) = 0

Solving
-3 + -1n + 4n2 = 0

Solving for variable 'n'.
