Solution for 5k^2+4k+10=0 equation:


Simplifying
5k2 + 4k + 10 = 0

Reorder the terms:
10 + 4k + 5k2 = 0

Solving
10 + 4k + 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'.
2 + 0.8k + k2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + 0.8k + -2 + k2 = 0 + -2

Reorder the terms:
2 + -2 + 0.8k + k2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 0.8k + k2 = 0 + -2
0.8k + k2 = 0 + -2

Combine like terms: 0 + -2 = -2
0.8k + k2 = -2

The k term is 0.8k.  Take half its coefficient (0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
0.8k + 0.16 + k2 = -2 + 0.16

Reorder the terms:
0.16 + 0.8k + k2 = -2 + 0.16

Combine like terms: -2 + 0.16 = -1.84
0.16 + 0.8k + k2 = -1.84

Factor a perfect square on the left side:
(k + 0.4)(k + 0.4) = -1.84

Can't calculate square root of the right side.

The solution to this equation could not be determined.
