Solution for 4w^2=4w-7 equation:


Simplifying
4w2 = 4w + -7

Reorder the terms:
4w2 = -7 + 4w

Solving
4w2 = -7 + 4w

Solving for variable 'w'.

Reorder the terms:
7 + -4w + 4w2 = -7 + 4w + 7 + -4w

Reorder the terms:
7 + -4w + 4w2 = -7 + 7 + 4w + -4w

Combine like terms: -7 + 7 = 0
7 + -4w + 4w2 = 0 + 4w + -4w
7 + -4w + 4w2 = 4w + -4w

Combine like terms: 4w + -4w = 0
7 + -4w + 4w2 = 0

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

Divide each side by '4'.
1.75 + -1w + w2 = 0

Move the constant term to the right:

Add '-1.75' to each side of the equation.
1.75 + -1w + -1.75 + w2 = 0 + -1.75

Reorder the terms:
1.75 + -1.75 + -1w + w2 = 0 + -1.75

Combine like terms: 1.75 + -1.75 = 0.00
0.00 + -1w + w2 = 0 + -1.75
-1w + w2 = 0 + -1.75

Combine like terms: 0 + -1.75 = -1.75
-1w + w2 = -1.75

The w term is -1w.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1w + 0.25 + w2 = -1.75 + 0.25

Reorder the terms:
0.25 + -1w + w2 = -1.75 + 0.25

Combine like terms: -1.75 + 0.25 = -1.5
0.25 + -1w + w2 = -1.5

Factor a perfect square on the left side:
(w + -0.5)(w + -0.5) = -1.5

Can't calculate square root of the right side.

The solution to this equation could not be determined.
