Solution for w^2-w-300=0 equation:


Simplifying
w2 + -1w + -300 = 0

Reorder the terms:
-300 + -1w + w2 = 0

Solving
-300 + -1w + w2 = 0

Solving for variable 'w'.

Begin completing the square.

Move the constant term to the right:

Add '300' to each side of the equation.
-300 + -1w + 300 + w2 = 0 + 300

Reorder the terms:
-300 + 300 + -1w + w2 = 0 + 300

Combine like terms: -300 + 300 = 0
0 + -1w + w2 = 0 + 300
-1w + w2 = 0 + 300

Combine like terms: 0 + 300 = 300
-1w + w2 = 300

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 = 300 + 0.25

Reorder the terms:
0.25 + -1w + w2 = 300 + 0.25

Combine like terms: 300 + 0.25 = 300.25
0.25 + -1w + w2 = 300.25

Factor a perfect square on the left side:
(w + -0.5)(w + -0.5) = 300.25

Calculate the square root of the right side: 17.327723451

Break this problem into two subproblems by setting 
(w + -0.5) equal to 17.327723451 and -17.327723451.

Subproblem 1

w + -0.5 = 17.327723451 Simplifying w + -0.5 = 17.327723451 Reorder the terms: -0.5 + w = 17.327723451 Solving -0.5 + w = 17.327723451 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = 17.327723451 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = 17.327723451 + 0.5 w = 17.327723451 + 0.5 Combine like terms: 17.327723451 + 0.5 = 17.827723451 w = 17.827723451 Simplifying w = 17.827723451

Subproblem 2

w + -0.5 = -17.327723451 Simplifying w + -0.5 = -17.327723451 Reorder the terms: -0.5 + w = -17.327723451 Solving -0.5 + w = -17.327723451 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = -17.327723451 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = -17.327723451 + 0.5 w = -17.327723451 + 0.5 Combine like terms: -17.327723451 + 0.5 = -16.827723451 w = -16.827723451 Simplifying w = -16.827723451
