Solution for 4=m-2m^2 equation:


Simplifying
4 = m + -2m2

Solving
4 = m + -2m2

Solving for variable 'm'.

Reorder the terms:
4 + -1m + 2m2 = m + -1m + -2m2 + 2m2

Combine like terms: m + -1m = 0
4 + -1m + 2m2 = 0 + -2m2 + 2m2
4 + -1m + 2m2 = -2m2 + 2m2

Combine like terms: -2m2 + 2m2 = 0
4 + -1m + 2m2 = 0

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
2 + -0.5m + m2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + -0.5m + -2 + m2 = 0 + -2

Reorder the terms:
2 + -2 + -0.5m + m2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -0.5m + m2 = 0 + -2
-0.5m + m2 = 0 + -2

Combine like terms: 0 + -2 = -2
-0.5m + m2 = -2

The m term is -0.5m.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5m + 0.0625 + m2 = -2 + 0.0625

Reorder the terms:
0.0625 + -0.5m + m2 = -2 + 0.0625

Combine like terms: -2 + 0.0625 = -1.9375
0.0625 + -0.5m + m2 = -1.9375

Factor a perfect square on the left side:
(m + -0.25)(m + -0.25) = -1.9375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
