Solution for m^2-m=-8 equation:


Simplifying
m2 + -1m = -8

Reorder the terms:
-1m + m2 = -8

Solving
-1m + m2 = -8

Solving for variable 'm'.

Reorder the terms:
8 + -1m + m2 = -8 + 8

Combine like terms: -8 + 8 = 0
8 + -1m + m2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-8' to each side of the equation.
8 + -1m + -8 + m2 = 0 + -8

Reorder the terms:
8 + -8 + -1m + m2 = 0 + -8

Combine like terms: 8 + -8 = 0
0 + -1m + m2 = 0 + -8
-1m + m2 = 0 + -8

Combine like terms: 0 + -8 = -8
-1m + m2 = -8

The m term is -1m.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1m + 0.25 + m2 = -8 + 0.25

Reorder the terms:
0.25 + -1m + m2 = -8 + 0.25

Combine like terms: -8 + 0.25 = -7.75
0.25 + -1m + m2 = -7.75

Factor a perfect square on the left side:
(m + -0.5)(m + -0.5) = -7.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
