(n-2)(7n-5)=0

Solution for (n-2)(7n-5)=0 equation:

Simplifying
(n + -2)(7n + -5) = 0

Reorder the terms:
(-2 + n)(7n + -5) = 0

Reorder the terms:
(-2 + n)(-5 + 7n) = 0

Multiply (-2 + n) * (-5 + 7n)
(-2(-5 + 7n) + n(-5 + 7n)) = 0
((-5 * -2 + 7n * -2) + n(-5 + 7n)) = 0
((10 + -14n) + n(-5 + 7n)) = 0
(10 + -14n + (-5 * n + 7n * n)) = 0
(10 + -14n + (-5n + 7n2)) = 0

Combine like terms: -14n + -5n = -19n
(10 + -19n + 7n2) = 0

Solving
10 + -19n + 7n2 = 0

Solving for variable 'n'.
