Solution for 10m^2+5=4m equation:


Simplifying
10m2 + 5 = 4m

Reorder the terms:
5 + 10m2 = 4m

Solving
5 + 10m2 = 4m

Solving for variable 'm'.

Reorder the terms:
5 + -4m + 10m2 = 4m + -4m

Combine like terms: 4m + -4m = 0
5 + -4m + 10m2 = 0

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

Divide each side by '10'.
0.5 + -0.4m + m2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -0.4m + -0.5 + m2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -0.4m + m2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -0.4m + m2 = 0 + -0.5
-0.4m + m2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-0.4m + m2 = -0.5

The m term is -0.4m.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4m + 0.04 + m2 = -0.5 + 0.04

Reorder the terms:
0.04 + -0.4m + m2 = -0.5 + 0.04

Combine like terms: -0.5 + 0.04 = -0.46
0.04 + -0.4m + m2 = -0.46

Factor a perfect square on the left side:
(m + -0.2)(m + -0.2) = -0.46

Can't calculate square root of the right side.

The solution to this equation could not be determined.
