Solution for [m+7][m-5]= equation:


Simplifying
[m + 7][m + -5] = 0

Reorder the terms:
[7 + m][m + -5] = 0

Reorder the terms:
[7 + m][-5 + m] = 0

Multiply [7 + m] * [-5 + m]
[7[-5 + m] + m[-5 + m]] = 0
[[-5 * 7 + m * 7] + m[-5 + m]] = 0
[[-35 + 7m] + m[-5 + m]] = 0
[-35 + 7m + [-5 * m + m * m]] = 0
[-35 + 7m + [-5m + m2]] = 0

Combine like terms: 7m + -5m = 2m
[-35 + 2m + m2] = 0

Solving
-35 + 2m + m2 = 0

Solving for variable 'm'.

Factor a trinomial.
