Solution for 5k*k+12k+16=0 equation:


Simplifying
5k * k + 12k + 16 = 0

Multiply k * k
5k2 + 12k + 16 = 0

Reorder the terms:
16 + 12k + 5k2 = 0

Solving
16 + 12k + 5k2 = 0

Solving for variable 'k'.

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

Divide each side by '5'.
3.2 + 2.4k + k2 = 0

Move the constant term to the right:

Add '-3.2' to each side of the equation.
3.2 + 2.4k + -3.2 + k2 = 0 + -3.2

Reorder the terms:
3.2 + -3.2 + 2.4k + k2 = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0
0.0 + 2.4k + k2 = 0 + -3.2
2.4k + k2 = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2
2.4k + k2 = -3.2

The k term is 2.4k.  Take half its coefficient (1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
2.4k + 1.44 + k2 = -3.2 + 1.44

Reorder the terms:
1.44 + 2.4k + k2 = -3.2 + 1.44

Combine like terms: -3.2 + 1.44 = -1.76
1.44 + 2.4k + k2 = -1.76

Factor a perfect square on the left side:
(k + 1.2)(k + 1.2) = -1.76

Can't calculate square root of the right side.

The solution to this equation could not be determined.
