Simplifying W2 + 6W + -10 = 0 Reorder the terms: -10 + 6W + W2 = 0 Solving -10 + 6W + W2 = 0 Solving for variable 'W'. Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + 6W + 10 + W2 = 0 + 10 Reorder the terms: -10 + 10 + 6W + W2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 6W + W2 = 0 + 10 6W + W2 = 0 + 10 Combine like terms: 0 + 10 = 10 6W + W2 = 10 The W term is 6W. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6W + 9 + W2 = 10 + 9 Reorder the terms: 9 + 6W + W2 = 10 + 9 Combine like terms: 10 + 9 = 19 9 + 6W + W2 = 19 Factor a perfect square on the left side: (W + 3)(W + 3) = 19 Calculate the square root of the right side: 4.358898944 Break this problem into two subproblems by setting (W + 3) equal to 4.358898944 and -4.358898944.Subproblem 1
W + 3 = 4.358898944 Simplifying W + 3 = 4.358898944 Reorder the terms: 3 + W = 4.358898944 Solving 3 + W = 4.358898944 Solving for variable 'W'. Move all terms containing W to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + W = 4.358898944 + -3 Combine like terms: 3 + -3 = 0 0 + W = 4.358898944 + -3 W = 4.358898944 + -3 Combine like terms: 4.358898944 + -3 = 1.358898944 W = 1.358898944 Simplifying W = 1.358898944Subproblem 2
W + 3 = -4.358898944 Simplifying W + 3 = -4.358898944 Reorder the terms: 3 + W = -4.358898944 Solving 3 + W = -4.358898944 Solving for variable 'W'. Move all terms containing W to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + W = -4.358898944 + -3 Combine like terms: 3 + -3 = 0 0 + W = -4.358898944 + -3 W = -4.358898944 + -3 Combine like terms: -4.358898944 + -3 = -7.358898944 W = -7.358898944 Simplifying W = -7.358898944Solution
The solution to the problem is based on the solutions from the subproblems. W = {1.358898944, -7.358898944}
