Solution for (m+16)*(m-4)=(m+12)*(m-2) equation:


Simplifying
(m + 16)(m + -4) = (m + 12)(m + -2)

Reorder the terms:
(16 + m)(m + -4) = (m + 12)(m + -2)

Reorder the terms:
(16 + m)(-4 + m) = (m + 12)(m + -2)

Multiply (16 + m) * (-4 + m)
(16(-4 + m) + m(-4 + m)) = (m + 12)(m + -2)
((-4 * 16 + m * 16) + m(-4 + m)) = (m + 12)(m + -2)
((-64 + 16m) + m(-4 + m)) = (m + 12)(m + -2)
(-64 + 16m + (-4 * m + m * m)) = (m + 12)(m + -2)
(-64 + 16m + (-4m + m2)) = (m + 12)(m + -2)

Combine like terms: 16m + -4m = 12m
(-64 + 12m + m2) = (m + 12)(m + -2)

Reorder the terms:
-64 + 12m + m2 = (12 + m)(m + -2)

Reorder the terms:
-64 + 12m + m2 = (12 + m)(-2 + m)

Multiply (12 + m) * (-2 + m)
-64 + 12m + m2 = (12(-2 + m) + m(-2 + m))
-64 + 12m + m2 = ((-2 * 12 + m * 12) + m(-2 + m))
-64 + 12m + m2 = ((-24 + 12m) + m(-2 + m))
-64 + 12m + m2 = (-24 + 12m + (-2 * m + m * m))
-64 + 12m + m2 = (-24 + 12m + (-2m + m2))

Combine like terms: 12m + -2m = 10m
-64 + 12m + m2 = (-24 + 10m + m2)

Add '-1m2' to each side of the equation.
-64 + 12m + m2 + -1m2 = -24 + 10m + m2 + -1m2

Combine like terms: m2 + -1m2 = 0
-64 + 12m + 0 = -24 + 10m + m2 + -1m2
-64 + 12m = -24 + 10m + m2 + -1m2

Combine like terms: m2 + -1m2 = 0
-64 + 12m = -24 + 10m + 0
-64 + 12m = -24 + 10m

Solving
-64 + 12m = -24 + 10m

Solving for variable 'm'.

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

Add '-10m' to each side of the equation.
-64 + 12m + -10m = -24 + 10m + -10m

Combine like terms: 12m + -10m = 2m
-64 + 2m = -24 + 10m + -10m

Combine like terms: 10m + -10m = 0
-64 + 2m = -24 + 0
-64 + 2m = -24

Add '64' to each side of the equation.
-64 + 64 + 2m = -24 + 64

Combine like terms: -64 + 64 = 0
0 + 2m = -24 + 64
2m = -24 + 64

Combine like terms: -24 + 64 = 40
2m = 40

Divide each side by '2'.
m = 20

Simplifying
m = 20
