(M+4)*(m+1)=

Solution for (M+4)*(m+1)= equation:

Simplifying
(M + 4)(m + 1) = 0

Reorder the terms:
(4 + M)(m + 1) = 0

Reorder the terms:
(4 + M)(1 + m) = 0

Multiply (4 + M) * (1 + m)
(4(1 + m) + M(1 + m)) = 0
((1 * 4 + m * 4) + M(1 + m)) = 0
((4 + 4m) + M(1 + m)) = 0
(4 + 4m + (1 * M + m * M)) = 0
(4 + 4m + (1M + mM)) = 0

Reorder the terms:
(4 + 1M + 4m + mM) = 0
(4 + 1M + 4m + mM) = 0

Solving
4 + 1M + 4m + mM = 0

Solving for variable 'M'.

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

Add '-4' to each side of the equation.
4 + 1M + 4m + -4 + mM = 0 + -4

Reorder the terms:
4 + -4 + 1M + 4m + mM = 0 + -4

Combine like terms: 4 + -4 = 0
0 + 1M + 4m + mM = 0 + -4
1M + 4m + mM = 0 + -4

Combine like terms: 0 + -4 = -4
1M + 4m + mM = -4

Add '-4m' to each side of the equation.
1M + 4m + -4m + mM = -4 + -4m

Combine like terms: 4m + -4m = 0
1M + 0 + mM = -4 + -4m
1M + mM = -4 + -4m

Reorder the terms:
4 + 1M + 4m + mM = -4 + -4m + 4 + 4m

Reorder the terms:
4 + 1M + 4m + mM = -4 + 4 + -4m + 4m

Combine like terms: -4 + 4 = 0
4 + 1M + 4m + mM = 0 + -4m + 4m
4 + 1M + 4m + mM = -4m + 4m

Combine like terms: -4m + 4m = 0
4 + 1M + 4m + mM = 0
