Simplifying w2 + -8w = 7 Reorder the terms: -8w + w2 = 7 Solving -8w + w2 = 7 Solving for variable 'w'. Reorder the terms: -7 + -8w + w2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + -8w + w2 = 0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + -8w + 7 + w2 = 0 + 7 Reorder the terms: -7 + 7 + -8w + w2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -8w + w2 = 0 + 7 -8w + w2 = 0 + 7 Combine like terms: 0 + 7 = 7 -8w + w2 = 7 The w term is -8w. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8w + 16 + w2 = 7 + 16 Reorder the terms: 16 + -8w + w2 = 7 + 16 Combine like terms: 7 + 16 = 23 16 + -8w + w2 = 23 Factor a perfect square on the left side: (w + -4)(w + -4) = 23 Calculate the square root of the right side: 4.795831523 Break this problem into two subproblems by setting (w + -4) equal to 4.795831523 and -4.795831523.Subproblem 1
w + -4 = 4.795831523 Simplifying w + -4 = 4.795831523 Reorder the terms: -4 + w = 4.795831523 Solving -4 + w = 4.795831523 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + w = 4.795831523 + 4 Combine like terms: -4 + 4 = 0 0 + w = 4.795831523 + 4 w = 4.795831523 + 4 Combine like terms: 4.795831523 + 4 = 8.795831523 w = 8.795831523 Simplifying w = 8.795831523Subproblem 2
w + -4 = -4.795831523 Simplifying w + -4 = -4.795831523 Reorder the terms: -4 + w = -4.795831523 Solving -4 + w = -4.795831523 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + w = -4.795831523 + 4 Combine like terms: -4 + 4 = 0 0 + w = -4.795831523 + 4 w = -4.795831523 + 4 Combine like terms: -4.795831523 + 4 = -0.795831523 w = -0.795831523 Simplifying w = -0.795831523Solution
The solution to the problem is based on the solutions from the subproblems. w = {8.795831523, -0.795831523}
