Solution for (m-12)(m-12)=225 equation:


Simplifying
(m + -12)(m + -12) = 225

Reorder the terms:
(-12 + m)(m + -12) = 225

Reorder the terms:
(-12 + m)(-12 + m) = 225

Multiply (-12 + m) * (-12 + m)
(-12(-12 + m) + m(-12 + m)) = 225
((-12 * -12 + m * -12) + m(-12 + m)) = 225
((144 + -12m) + m(-12 + m)) = 225
(144 + -12m + (-12 * m + m * m)) = 225
(144 + -12m + (-12m + m2)) = 225

Combine like terms: -12m + -12m = -24m
(144 + -24m + m2) = 225

Solving
144 + -24m + m2 = 225

Solving for variable 'm'.
