(M+13)(m+4)=0

Solution for (M+13)(m+4)=0 equation:

Simplifying
(M + 13)(m + 4) = 0

Reorder the terms:
(13 + M)(m + 4) = 0

Reorder the terms:
(13 + M)(4 + m) = 0

Multiply (13 + M) * (4 + m)
(13(4 + m) + M(4 + m)) = 0
((4 * 13 + m * 13) + M(4 + m)) = 0
((52 + 13m) + M(4 + m)) = 0
(52 + 13m + (4 * M + m * M)) = 0
(52 + 13m + (4M + mM)) = 0

Reorder the terms:
(52 + 4M + 13m + mM) = 0
(52 + 4M + 13m + mM) = 0

Solving
52 + 4M + 13m + mM = 0

Solving for variable 'M'.

Move all terms containing M to the left, all other terms to the right.

Add '-52' to each side of the equation.
52 + 4M + 13m + -52 + mM = 0 + -52

Reorder the terms:
52 + -52 + 4M + 13m + mM = 0 + -52

Combine like terms: 52 + -52 = 0
0 + 4M + 13m + mM = 0 + -52
4M + 13m + mM = 0 + -52

Combine like terms: 0 + -52 = -52
4M + 13m + mM = -52

Add '-13m' to each side of the equation.
4M + 13m + -13m + mM = -52 + -13m

Combine like terms: 13m + -13m = 0
4M + 0 + mM = -52 + -13m
4M + mM = -52 + -13m

Reorder the terms:
52 + 4M + 13m + mM = -52 + -13m + 52 + 13m

Reorder the terms:
52 + 4M + 13m + mM = -52 + 52 + -13m + 13m

Combine like terms: -52 + 52 = 0
52 + 4M + 13m + mM = 0 + -13m + 13m
52 + 4M + 13m + mM = -13m + 13m

Combine like terms: -13m + 13m = 0
52 + 4M + 13m + mM = 0
