Simplifying j2 + 8j + 8 = 0 Reorder the terms: 8 + 8j + j2 = 0 Solving 8 + 8j + j2 = 0 Solving for variable 'j'. Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + 8j + -8 + j2 = 0 + -8 Reorder the terms: 8 + -8 + 8j + j2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 8j + j2 = 0 + -8 8j + j2 = 0 + -8 Combine like terms: 0 + -8 = -8 8j + j2 = -8 The j term is 8j. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8j + 16 + j2 = -8 + 16 Reorder the terms: 16 + 8j + j2 = -8 + 16 Combine like terms: -8 + 16 = 8 16 + 8j + j2 = 8 Factor a perfect square on the left side: (j + 4)(j + 4) = 8 Calculate the square root of the right side: 2.828427125 Break this problem into two subproblems by setting (j + 4) equal to 2.828427125 and -2.828427125.Subproblem 1
j + 4 = 2.828427125 Simplifying j + 4 = 2.828427125 Reorder the terms: 4 + j = 2.828427125 Solving 4 + j = 2.828427125 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + j = 2.828427125 + -4 Combine like terms: 4 + -4 = 0 0 + j = 2.828427125 + -4 j = 2.828427125 + -4 Combine like terms: 2.828427125 + -4 = -1.171572875 j = -1.171572875 Simplifying j = -1.171572875Subproblem 2
j + 4 = -2.828427125 Simplifying j + 4 = -2.828427125 Reorder the terms: 4 + j = -2.828427125 Solving 4 + j = -2.828427125 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + j = -2.828427125 + -4 Combine like terms: 4 + -4 = 0 0 + j = -2.828427125 + -4 j = -2.828427125 + -4 Combine like terms: -2.828427125 + -4 = -6.828427125 j = -6.828427125 Simplifying j = -6.828427125Solution
