Solution for 2m^2-m+9=0 equation:


Simplifying
2m2 + -1m + 9 = 0

Reorder the terms:
9 + -1m + 2m2 = 0

Solving
9 + -1m + 2m2 = 0

Solving for variable 'm'.

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

Divide each side by '2'.
4.5 + -0.5m + m2 = 0

Move the constant term to the right:

Add '-4.5' to each side of the equation.
4.5 + -0.5m + -4.5 + m2 = 0 + -4.5

Reorder the terms:
4.5 + -4.5 + -0.5m + m2 = 0 + -4.5

Combine like terms: 4.5 + -4.5 = 0.0
0.0 + -0.5m + m2 = 0 + -4.5
-0.5m + m2 = 0 + -4.5

Combine like terms: 0 + -4.5 = -4.5
-0.5m + m2 = -4.5

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 = -4.5 + 0.0625

Reorder the terms:
0.0625 + -0.5m + m2 = -4.5 + 0.0625

Combine like terms: -4.5 + 0.0625 = -4.4375
0.0625 + -0.5m + m2 = -4.4375

Factor a perfect square on the left side:
(m + -0.25)(m + -0.25) = -4.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
