Simplifying w2 + -4w + 4 = 11 Reorder the terms: 4 + -4w + w2 = 11 Solving 4 + -4w + w2 = 11 Solving for variable 'w'. Reorder the terms: 4 + -11 + -4w + w2 = 11 + -11 Combine like terms: 4 + -11 = -7 -7 + -4w + w2 = 11 + -11 Combine like terms: 11 + -11 = 0 -7 + -4w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + -4w + 7 + w2 = 0 + 7 Reorder the terms: -7 + 7 + -4w + w2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -4w + w2 = 0 + 7 -4w + w2 = 0 + 7 Combine like terms: 0 + 7 = 7 -4w + w2 = 7 The w term is -4w. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4w + 4 + w2 = 7 + 4 Reorder the terms: 4 + -4w + w2 = 7 + 4 Combine like terms: 7 + 4 = 11 4 + -4w + w2 = 11 Factor a perfect square on the left side: (w + -2)(w + -2) = 11 Calculate the square root of the right side: 3.31662479 Break this problem into two subproblems by setting (w + -2) equal to 3.31662479 and -3.31662479.Subproblem 1
w + -2 = 3.31662479 Simplifying w + -2 = 3.31662479 Reorder the terms: -2 + w = 3.31662479 Solving -2 + w = 3.31662479 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + w = 3.31662479 + 2 Combine like terms: -2 + 2 = 0 0 + w = 3.31662479 + 2 w = 3.31662479 + 2 Combine like terms: 3.31662479 + 2 = 5.31662479 w = 5.31662479 Simplifying w = 5.31662479Subproblem 2
w + -2 = -3.31662479 Simplifying w + -2 = -3.31662479 Reorder the terms: -2 + w = -3.31662479 Solving -2 + w = -3.31662479 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + w = -3.31662479 + 2 Combine like terms: -2 + 2 = 0 0 + w = -3.31662479 + 2 w = -3.31662479 + 2 Combine like terms: -3.31662479 + 2 = -1.31662479 w = -1.31662479 Simplifying w = -1.31662479Solution
The solution to the problem is based on the solutions from the subproblems. w = {5.31662479, -1.31662479}
