Solution for (3m+n)(3m+n)= equation:


Simplifying
(3m + n)(3m + n) = 0

Multiply (3m + n) * (3m + n)
(3m * (3m + n) + n(3m + n)) = 0
((3m * 3m + n * 3m) + n(3m + n)) = 0

Reorder the terms:
((3mn + 9m2) + n(3m + n)) = 0
((3mn + 9m2) + n(3m + n)) = 0
(3mn + 9m2 + (3m * n + n * n)) = 0
(3mn + 9m2 + (3mn + n2)) = 0

Reorder the terms:
(3mn + 3mn + 9m2 + n2) = 0

Combine like terms: 3mn + 3mn = 6mn
(6mn + 9m2 + n2) = 0

Solving
6mn + 9m2 + n2 = 0

Solving for variable 'm'.
