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

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

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

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

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

Multiply (-5 + 2n) * (-2 + n)
(-5(-2 + n) + 2n * (-2 + n)) = 0
((-2 * -5 + n * -5) + 2n * (-2 + n)) = 0
((10 + -5n) + 2n * (-2 + n)) = 0
(10 + -5n + (-2 * 2n + n * 2n)) = 0
(10 + -5n + (-4n + 2n2)) = 0

Combine like terms: -5n + -4n = -9n
(10 + -9n + 2n2) = 0

Solving
10 + -9n + 2n2 = 0

Solving for variable 'n'.
