Solution for -4k+3+k^2-k+8= equation:


Simplifying
-4k + 3 + k2 + -1k + 8 = 0

Reorder the terms:
3 + 8 + -4k + -1k + k2 = 0

Combine like terms: 3 + 8 = 11
11 + -4k + -1k + k2 = 0

Combine like terms: -4k + -1k = -5k
11 + -5k + k2 = 0

Solving
11 + -5k + k2 = 0

Solving for variable 'k'.

Begin completing the square.

Move the constant term to the right:

Add '-11' to each side of the equation.
11 + -5k + -11 + k2 = 0 + -11

Reorder the terms:
11 + -11 + -5k + k2 = 0 + -11

Combine like terms: 11 + -11 = 0
0 + -5k + k2 = 0 + -11
-5k + k2 = 0 + -11

Combine like terms: 0 + -11 = -11
-5k + k2 = -11

The k term is -5k.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5k + 6.25 + k2 = -11 + 6.25

Reorder the terms:
6.25 + -5k + k2 = -11 + 6.25

Combine like terms: -11 + 6.25 = -4.75
6.25 + -5k + k2 = -4.75

Factor a perfect square on the left side:
(k + -2.5)(k + -2.5) = -4.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
