Solution for 25k^2-22k+7=0 equation: 


Simplifying
25k2 + -22k + 7 = 0

Reorder the terms:
7 + -22k + 25k2 = 0

Solving
7 + -22k + 25k2 = 0

Solving for variable 'k'.

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

Divide each side by '25'.
0.28 + -0.88k + k2 = 0

Move the constant term to the right:

Add '-0.28' to each side of the equation.
0.28 + -0.88k + -0.28 + k2 = 0 + -0.28

Reorder the terms:
0.28 + -0.28 + -0.88k + k2 = 0 + -0.28

Combine like terms: 0.28 + -0.28 = 0.00
0.00 + -0.88k + k2 = 0 + -0.28
-0.88k + k2 = 0 + -0.28

Combine like terms: 0 + -0.28 = -0.28
-0.88k + k2 = -0.28

The k term is -0.88k.  Take half its coefficient (-0.44).
Square it (0.1936) and add it to both sides.

Add '0.1936' to each side of the equation.
-0.88k + 0.1936 + k2 = -0.28 + 0.1936

Reorder the terms:
0.1936 + -0.88k + k2 = -0.28 + 0.1936

Combine like terms: -0.28 + 0.1936 = -0.0864
0.1936 + -0.88k + k2 = -0.0864

Factor a perfect square on the left side:
(k + -0.44)(k + -0.44) = -0.0864

Can't calculate square root of the right side.

The solution to this equation could not be determined.
