-8 + 9 + 6X + 2X2 + -1X2 = 5X

Combine like terms: -8 + 9 = 1
1 + 6X + 2X2 + -1X2 = 5X

Combine like terms: 2X2 + -1X2 = 1X2
1 + 6X + 1X2 = 5X

Solving
1 + 6X + 1X2 = 5X

Solving for variable 'X'.

Reorder the terms:
1 + 6X + -5X + 1X2 = 5X + -5X

Combine like terms: 6X + -5X = 1X
1 + 1X + 1X2 = 5X + -5X

Combine like terms: 5X + -5X = 0
1 + 1X + 1X2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 1X + -1 + X2 = 0 + -1

Reorder the terms:
1 + -1 + 1X + X2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 1X + X2 = 0 + -1
1X + X2 = 0 + -1

Combine like terms: 0 + -1 = -1
1X + X2 = -1

The X term is 1X.  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.
X + 0.25 + X2 = -1 + 0.25

Reorder the terms:
0.25 + X + X2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + X + X2 = -0.75

Factor a perfect square on the left side:
(X + 0.5)(X + 0.5) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
