(m+5)(m-5)=

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

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

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

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

Multiply (5 + m) * (-5 + m)
(5(-5 + m) + m(-5 + m)) = 0
((-5 * 5 + m * 5) + m(-5 + m)) = 0
((-25 + 5m) + m(-5 + m)) = 0
(-25 + 5m + (-5 * m + m * m)) = 0
(-25 + 5m + (-5m + m2)) = 0

Combine like terms: 5m + -5m = 0
(-25 + 0 + m2) = 0
(-25 + m2) = 0

Solving
-25 + m2 = 0

Solving for variable 'm'.

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

Add '25' to each side of the equation.
-25 + 25 + m2 = 0 + 25

Combine like terms: -25 + 25 = 0
0 + m2 = 0 + 25
m2 = 0 + 25

Combine like terms: 0 + 25 = 25
m2 = 25

Simplifying
m2 = 25

Take the square root of each side:
m = {-5, 5}
