Solution for (9+2w)(w-4)=110 equation:


Simplifying
(9 + 2w)(w + -4) = 110

Reorder the terms:
(9 + 2w)(-4 + w) = 110

Multiply (9 + 2w) * (-4 + w)
(9(-4 + w) + 2w * (-4 + w)) = 110
((-4 * 9 + w * 9) + 2w * (-4 + w)) = 110
((-36 + 9w) + 2w * (-4 + w)) = 110
(-36 + 9w + (-4 * 2w + w * 2w)) = 110
(-36 + 9w + (-8w + 2w2)) = 110

Combine like terms: 9w + -8w = 1w
(-36 + 1w + 2w2) = 110

Solving
-36 + 1w + 2w2 = 110

Solving for variable 'w'.

Reorder the terms:
-36 + -110 + 1w + 2w2 = 110 + -110

Combine like terms: -36 + -110 = -146
-146 + 1w + 2w2 = 110 + -110

Combine like terms: 110 + -110 = 0
-146 + 1w + 2w2 = 0

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

Divide each side by '2'.
-73 + 0.5w + w2 = 0

Move the constant term to the right:

Add '73' to each side of the equation.
-73 + 0.5w + 73 + w2 = 0 + 73

Reorder the terms:
-73 + 73 + 0.5w + w2 = 0 + 73

Combine like terms: -73 + 73 = 0
0 + 0.5w + w2 = 0 + 73
0.5w + w2 = 0 + 73

Combine like terms: 0 + 73 = 73
0.5w + w2 = 73

The w term is 0.5w.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5w + 0.0625 + w2 = 73 + 0.0625

Reorder the terms:
0.0625 + 0.5w + w2 = 73 + 0.0625

Combine like terms: 73 + 0.0625 = 73.0625
0.0625 + 0.5w + w2 = 73.0625

Factor a perfect square on the left side:
(w + 0.25)(w + 0.25) = 73.0625

Calculate the square root of the right side: 8.547660499

Break this problem into two subproblems by setting 
(w + 0.25) equal to 8.547660499 and -8.547660499.

Subproblem 1

w + 0.25 = 8.547660499 Simplifying w + 0.25 = 8.547660499 Reorder the terms: 0.25 + w = 8.547660499 Solving 0.25 + w = 8.547660499 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + w = 8.547660499 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + w = 8.547660499 + -0.25 w = 8.547660499 + -0.25 Combine like terms: 8.547660499 + -0.25 = 8.297660499 w = 8.297660499 Simplifying w = 8.297660499

Subproblem 2

w + 0.25 = -8.547660499 Simplifying w + 0.25 = -8.547660499 Reorder the terms: 0.25 + w = -8.547660499 Solving 0.25 + w = -8.547660499 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + w = -8.547660499 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + w = -8.547660499 + -0.25 w = -8.547660499 + -0.25 Combine like terms: -8.547660499 + -0.25 = -8.797660499 w = -8.797660499 Simplifying w = -8.797660499
