Solution for (2m+1)(m-2)=m(2m-4) equation:


Simplifying
(2m + 1)(m + -2) = m(2m + -4)

Reorder the terms:
(1 + 2m)(m + -2) = m(2m + -4)

Reorder the terms:
(1 + 2m)(-2 + m) = m(2m + -4)

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

Combine like terms: 1m + -4m = -3m
(-2 + -3m + 2m2) = m(2m + -4)

Reorder the terms:
-2 + -3m + 2m2 = m(-4 + 2m)
-2 + -3m + 2m2 = (-4 * m + 2m * m)
-2 + -3m + 2m2 = (-4m + 2m2)

Add '-2m2' to each side of the equation.
-2 + -3m + 2m2 + -2m2 = -4m + 2m2 + -2m2

Combine like terms: 2m2 + -2m2 = 0
-2 + -3m + 0 = -4m + 2m2 + -2m2
-2 + -3m = -4m + 2m2 + -2m2

Combine like terms: 2m2 + -2m2 = 0
-2 + -3m = -4m + 0
-2 + -3m = -4m

Solving
-2 + -3m = -4m

Solving for variable 'm'.

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

Add '4m' to each side of the equation.
-2 + -3m + 4m = -4m + 4m

Combine like terms: -3m + 4m = 1m
-2 + 1m = -4m + 4m

Combine like terms: -4m + 4m = 0
-2 + 1m = 0

Add '2' to each side of the equation.
-2 + 2 + 1m = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 1m = 0 + 2
1m = 0 + 2

Combine like terms: 0 + 2 = 2
1m = 2

Divide each side by '1'.
m = 2

Simplifying
m = 2
