Solution for (m+2)(2m-6)=5(m-1)-12 equation:


Simplifying
(m + 2)(2m + -6) = 5(m + -1) + -12

Reorder the terms:
(2 + m)(2m + -6) = 5(m + -1) + -12

Reorder the terms:
(2 + m)(-6 + 2m) = 5(m + -1) + -12

Multiply (2 + m) * (-6 + 2m)
(2(-6 + 2m) + m(-6 + 2m)) = 5(m + -1) + -12
((-6 * 2 + 2m * 2) + m(-6 + 2m)) = 5(m + -1) + -12
((-12 + 4m) + m(-6 + 2m)) = 5(m + -1) + -12
(-12 + 4m + (-6 * m + 2m * m)) = 5(m + -1) + -12
(-12 + 4m + (-6m + 2m2)) = 5(m + -1) + -12

Combine like terms: 4m + -6m = -2m
(-12 + -2m + 2m2) = 5(m + -1) + -12

Reorder the terms:
-12 + -2m + 2m2 = 5(-1 + m) + -12
-12 + -2m + 2m2 = (-1 * 5 + m * 5) + -12
-12 + -2m + 2m2 = (-5 + 5m) + -12
