Simplifying 28.1 = 114I + -100I2 Solving 28.1 = 114I + -100I2 Solving for variable 'I'. Reorder the terms: 28.1 + -114I + 100I2 = 114I + -114I + -100I2 + 100I2 Combine like terms: 114I + -114I = 0 28.1 + -114I + 100I2 = 0 + -100I2 + 100I2 28.1 + -114I + 100I2 = -100I2 + 100I2 Combine like terms: -100I2 + 100I2 = 0 28.1 + -114I + 100I2 = 0 Begin completing the square. Divide all terms by 100 the coefficient of the squared term: Divide each side by '100'. 0.281 + -1.14I + I2 = 0 Move the constant term to the right: Add '-0.281' to each side of the equation. 0.281 + -1.14I + -0.281 + I2 = 0 + -0.281 Reorder the terms: 0.281 + -0.281 + -1.14I + I2 = 0 + -0.281 Combine like terms: 0.281 + -0.281 = 0.000 0.000 + -1.14I + I2 = 0 + -0.281 -1.14I + I2 = 0 + -0.281 Combine like terms: 0 + -0.281 = -0.281 -1.14I + I2 = -0.281 The I term is -1.14I. Take half its coefficient (-0.57). Square it (0.3249) and add it to both sides. Add '0.3249' to each side of the equation. -1.14I + 0.3249 + I2 = -0.281 + 0.3249 Reorder the terms: 0.3249 + -1.14I + I2 = -0.281 + 0.3249 Combine like terms: -0.281 + 0.3249 = 0.0439 0.3249 + -1.14I + I2 = 0.0439 Factor a perfect square on the left side: (I + -0.57)(I + -0.57) = 0.0439 Calculate the square root of the right side: 0.209523268 Break this problem into two subproblems by setting (I + -0.57) equal to 0.209523268 and -0.209523268.Subproblem 1
I + -0.57 = 0.209523268 Simplifying I + -0.57 = 0.209523268 Reorder the terms: -0.57 + I = 0.209523268 Solving -0.57 + I = 0.209523268 Solving for variable 'I'. Move all terms containing I to the left, all other terms to the right. Add '0.57' to each side of the equation. -0.57 + 0.57 + I = 0.209523268 + 0.57 Combine like terms: -0.57 + 0.57 = 0.00 0.00 + I = 0.209523268 + 0.57 I = 0.209523268 + 0.57 Combine like terms: 0.209523268 + 0.57 = 0.779523268 I = 0.779523268 Simplifying I = 0.779523268Subproblem 2
I + -0.57 = -0.209523268 Simplifying I + -0.57 = -0.209523268 Reorder the terms: -0.57 + I = -0.209523268 Solving -0.57 + I = -0.209523268 Solving for variable 'I'. Move all terms containing I to the left, all other terms to the right. Add '0.57' to each side of the equation. -0.57 + 0.57 + I = -0.209523268 + 0.57 Combine like terms: -0.57 + 0.57 = 0.00 0.00 + I = -0.209523268 + 0.57 I = -0.209523268 + 0.57 Combine like terms: -0.209523268 + 0.57 = 0.360476732 I = 0.360476732 Simplifying I = 0.360476732Solution
