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

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

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

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

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

Multiply (-3 + 3n) * (1 + 4n)
(-3(1 + 4n) + 3n * (1 + 4n)) = 0
((1 * -3 + 4n * -3) + 3n * (1 + 4n)) = 0
((-3 + -12n) + 3n * (1 + 4n)) = 0
(-3 + -12n + (1 * 3n + 4n * 3n)) = 0
(-3 + -12n + (3n + 12n2)) = 0

Combine like terms: -12n + 3n = -9n
(-3 + -9n + 12n2) = 0

Solving
-3 + -9n + 12n2 = 0
