Solution for (M-1)(m+1)= equation:


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

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

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

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

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

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

Solving for variable 'M'.

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

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

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

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

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

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

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

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

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

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

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