Simplifying j * j + j = 50 Multiply j * j j2 + j = 50 Reorder the terms: j + j2 = 50 Solving j + j2 = 50 Solving for variable 'j'. Reorder the terms: -50 + j + j2 = 50 + -50 Combine like terms: 50 + -50 = 0 -50 + j + j2 = 0 Begin completing the square. Move the constant term to the right: Add '50' to each side of the equation. -50 + j + 50 + j2 = 0 + 50 Reorder the terms: -50 + 50 + j + j2 = 0 + 50 Combine like terms: -50 + 50 = 0 0 + j + j2 = 0 + 50 j + j2 = 0 + 50 Combine like terms: 0 + 50 = 50 j + j2 = 50 The j term is j. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. j + 0.25 + j2 = 50 + 0.25 Reorder the terms: 0.25 + j + j2 = 50 + 0.25 Combine like terms: 50 + 0.25 = 50.25 0.25 + j + j2 = 50.25 Factor a perfect square on the left side: (j + 0.5)(j + 0.5) = 50.25 Calculate the square root of the right side: 7.088723439 Break this problem into two subproblems by setting (j + 0.5) equal to 7.088723439 and -7.088723439.Subproblem 1
j + 0.5 = 7.088723439 Simplifying j + 0.5 = 7.088723439 Reorder the terms: 0.5 + j = 7.088723439 Solving 0.5 + j = 7.088723439 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + j = 7.088723439 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + j = 7.088723439 + -0.5 j = 7.088723439 + -0.5 Combine like terms: 7.088723439 + -0.5 = 6.588723439 j = 6.588723439 Simplifying j = 6.588723439Subproblem 2
j + 0.5 = -7.088723439 Simplifying j + 0.5 = -7.088723439 Reorder the terms: 0.5 + j = -7.088723439 Solving 0.5 + j = -7.088723439 Solving for variable 'j'. Move all terms containing j to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + j = -7.088723439 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + j = -7.088723439 + -0.5 j = -7.088723439 + -0.5 Combine like terms: -7.088723439 + -0.5 = -7.588723439 j = -7.588723439 Simplifying j = -7.588723439Solution
The solution to the problem is based on the solutions from the subproblems. j = {6.588723439, -7.588723439}
