(9n-2)(n-5)=0

Solution for (9n-2)(n-5)=0 equation:

Simplifying
(9n + -2)(n + -5) = 0

Reorder the terms:
(-2 + 9n)(n + -5) = 0

Reorder the terms:
(-2 + 9n)(-5 + n) = 0

Multiply (-2 + 9n) * (-5 + n)
(-2(-5 + n) + 9n * (-5 + n)) = 0
((-5 * -2 + n * -2) + 9n * (-5 + n)) = 0
((10 + -2n) + 9n * (-5 + n)) = 0
(10 + -2n + (-5 * 9n + n * 9n)) = 0
(10 + -2n + (-45n + 9n2)) = 0

Combine like terms: -2n + -45n = -47n
(10 + -47n + 9n2) = 0

Solving
10 + -47n + 9n2 = 0

Solving for variable 'n'.
