w^2-2w+143=0

Solution for w^2-2w+143=0 equation:

Simplifying
w2 + -2w + 143 = 0

Reorder the terms:
143 + -2w + w2 = 0

Solving
143 + -2w + w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '-143' to each side of the equation.
143 + -2w + -143 + w2 = 0 + -143

Reorder the terms:
143 + -143 + -2w + w2 = 0 + -143

Combine like terms: 143 + -143 = 0
0 + -2w + w2 = 0 + -143
-2w + w2 = 0 + -143

Combine like terms: 0 + -143 = -143
-2w + w2 = -143

The w term is -2w.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2w + 1 + w2 = -143 + 1

Reorder the terms:
1 + -2w + w2 = -143 + 1

Combine like terms: -143 + 1 = -142
1 + -2w + w2 = -142

Factor a perfect square on the left side:
(w + -1)(w + -1) = -142

Can't calculate square root of the right side.

The solution to this equation could not be determined.
