Solution for (n-3)(n-3)=3 equation:


Simplifying
(n + -3)(n + -3) = 3

Reorder the terms:
(-3 + n)(n + -3) = 3

Reorder the terms:
(-3 + n)(-3 + n) = 3

Multiply (-3 + n) * (-3 + n)
(-3(-3 + n) + n(-3 + n)) = 3
((-3 * -3 + n * -3) + n(-3 + n)) = 3
((9 + -3n) + n(-3 + n)) = 3
(9 + -3n + (-3 * n + n * n)) = 3
(9 + -3n + (-3n + n2)) = 3

Combine like terms: -3n + -3n = -6n
(9 + -6n + n2) = 3

Solving
9 + -6n + n2 = 3

Solving for variable 'n'.

Reorder the terms:
9 + -3 + -6n + n2 = 3 + -3

Combine like terms: 9 + -3 = 6
6 + -6n + n2 = 3 + -3
