(m-1)(m+5)=0

Solution for (m-1)(m+5)=0 equation:

Simplifying
(m + -1)(m + 5) = 0

Reorder the terms:
(-1 + m)(m + 5) = 0

Reorder the terms:
(-1 + m)(5 + m) = 0

Multiply (-1 + m) * (5 + m)
(-1(5 + m) + m(5 + m)) = 0
((5 * -1 + m * -1) + m(5 + m)) = 0
((-5 + -1m) + m(5 + m)) = 0
(-5 + -1m + (5 * m + m * m)) = 0
(-5 + -1m + (5m + m2)) = 0

Combine like terms: -1m + 5m = 4m
(-5 + 4m + m2) = 0

Solving
-5 + 4m + m2 = 0

Solving for variable 'm'.

Factor a trinomial.
(-5 + -1m)(1 + -1m) = 0

Subproblem 1
Set the factor '(-5 + -1m)' equal to zero and attempt to solve:

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

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

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

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

Divide each side by '-1'.
m = 1

Simplifying
m = 1
Solution
m = {-5, 1}
