Solution for 4k^2+5=3k equation:


Simplifying
4k2 + 5 = 3k

Reorder the terms:
5 + 4k2 = 3k

Solving
5 + 4k2 = 3k

Solving for variable 'k'.

Reorder the terms:
5 + -3k + 4k2 = 3k + -3k

Combine like terms: 3k + -3k = 0
5 + -3k + 4k2 = 0

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

Divide each side by '4'.
1.25 + -0.75k + k2 = 0

Move the constant term to the right:

Add '-1.25' to each side of the equation.
1.25 + -0.75k + -1.25 + k2 = 0 + -1.25

Reorder the terms:
1.25 + -1.25 + -0.75k + k2 = 0 + -1.25

Combine like terms: 1.25 + -1.25 = 0.00
0.00 + -0.75k + k2 = 0 + -1.25
-0.75k + k2 = 0 + -1.25

Combine like terms: 0 + -1.25 = -1.25
-0.75k + k2 = -1.25

The k term is -0.75k.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75k + 0.140625 + k2 = -1.25 + 0.140625

Reorder the terms:
0.140625 + -0.75k + k2 = -1.25 + 0.140625

Combine like terms: -1.25 + 0.140625 = -1.109375
0.140625 + -0.75k + k2 = -1.109375

Factor a perfect square on the left side:
(k + -0.375)(k + -0.375) = -1.109375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
