Solution for (m-7)(m-7)=49 equation:


Simplifying
(m + -7)(m + -7) = 49

Reorder the terms:
(-7 + m)(m + -7) = 49

Reorder the terms:
(-7 + m)(-7 + m) = 49

Multiply (-7 + m) * (-7 + m)
(-7(-7 + m) + m(-7 + m)) = 49
((-7 * -7 + m * -7) + m(-7 + m)) = 49
((49 + -7m) + m(-7 + m)) = 49
(49 + -7m + (-7 * m + m * m)) = 49
(49 + -7m + (-7m + m2)) = 49

Combine like terms: -7m + -7m = -14m
(49 + -14m + m2) = 49

Add '-49' to each side of the equation.
49 + -14m + -49 + m2 = 49 + -49

Reorder the terms:
49 + -49 + -14m + m2 = 49 + -49

Combine like terms: 49 + -49 = 0
0 + -14m + m2 = 49 + -49
-14m + m2 = 49 + -49

Combine like terms: 49 + -49 = 0
-14m + m2 = 0

Solving
-14m + m2 = 0
