Simplifying -5j2 + 9j + 7 = 0 Reorder the terms: 7 + 9j + -5j2 = 0 Solving 7 + 9j + -5j2 = 0 Solving for variable 'j'. Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.4 + -1.8j + j2 = 0 Move the constant term to the right: Add '1.4' to each side of the equation. -1.4 + -1.8j + 1.4 + j2 = 0 + 1.4 Reorder the terms: -1.4 + 1.4 + -1.8j + j2 = 0 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + -1.8j + j2 = 0 + 1.4 -1.8j + j2 = 0 + 1.4 Combine like terms: 0 + 1.4 = 1.4 -1.8j + j2 = 1.4 The j term is -1.8j. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8j + 0.81 + j2 = 1.4 + 0.81 Reorder the terms: 0.81 + -1.8j + j2 = 1.4 + 0.81 Combine like terms: 1.4 + 0.81 = 2.21 0.81 + -1.8j + j2 = 2.21 Factor a perfect square on the left side: (j + -0.9)(j + -0.9) = 2.21 Calculate the square root of the right side: 1.486606875 Break this problem into two subproblems by setting (j + -0.9) equal to 1.486606875 and -1.486606875.Subproblem 1
j + -0.9 = 1.486606875 Simplifying j + -0.9 = 1.486606875 Reorder the terms: -0.9 + j = 1.486606875 Solving -0.9 + j = 1.486606875 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + j = 1.486606875 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + j = 1.486606875 + 0.9 j = 1.486606875 + 0.9 Combine like terms: 1.486606875 + 0.9 = 2.386606875 j = 2.386606875 Simplifying j = 2.386606875Subproblem 2
j + -0.9 = -1.486606875 Simplifying j + -0.9 = -1.486606875 Reorder the terms: -0.9 + j = -1.486606875 Solving -0.9 + j = -1.486606875 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + j = -1.486606875 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + j = -1.486606875 + 0.9 j = -1.486606875 + 0.9 Combine like terms: -1.486606875 + 0.9 = -0.586606875 j = -0.586606875 Simplifying j = -0.586606875Solution
The solution to the problem is based on the solutions from the subproblems. j = {2.386606875, -0.586606875}
