Simplifying 2x2 + 38x + -361 = 0 Reorder the terms: -361 + 38x + 2x2 = 0 Solving -361 + 38x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -180.5 + 19x + x2 = 0 Move the constant term to the right: Add '180.5' to each side of the equation. -180.5 + 19x + 180.5 + x2 = 0 + 180.5 Reorder the terms: -180.5 + 180.5 + 19x + x2 = 0 + 180.5 Combine like terms: -180.5 + 180.5 = 0.0 0.0 + 19x + x2 = 0 + 180.5 19x + x2 = 0 + 180.5 Combine like terms: 0 + 180.5 = 180.5 19x + x2 = 180.5 The x term is 19x. Take half its coefficient (9.5). Square it (90.25) and add it to both sides. Add '90.25' to each side of the equation. 19x + 90.25 + x2 = 180.5 + 90.25 Reorder the terms: 90.25 + 19x + x2 = 180.5 + 90.25 Combine like terms: 180.5 + 90.25 = 270.75 90.25 + 19x + x2 = 270.75 Factor a perfect square on the left side: (x + 9.5)(x + 9.5) = 270.75 Calculate the square root of the right side: 16.454482672 Break this problem into two subproblems by setting (x + 9.5) equal to 16.454482672 and -16.454482672.Subproblem 1
x + 9.5 = 16.454482672 Simplifying x + 9.5 = 16.454482672 Reorder the terms: 9.5 + x = 16.454482672 Solving 9.5 + x = 16.454482672 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = 16.454482672 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = 16.454482672 + -9.5 x = 16.454482672 + -9.5 Combine like terms: 16.454482672 + -9.5 = 6.954482672 x = 6.954482672 Simplifying x = 6.954482672Subproblem 2
x + 9.5 = -16.454482672 Simplifying x + 9.5 = -16.454482672 Reorder the terms: 9.5 + x = -16.454482672 Solving 9.5 + x = -16.454482672 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9.5' to each side of the equation. 9.5 + -9.5 + x = -16.454482672 + -9.5 Combine like terms: 9.5 + -9.5 = 0.0 0.0 + x = -16.454482672 + -9.5 x = -16.454482672 + -9.5 Combine like terms: -16.454482672 + -9.5 = -25.954482672 x = -25.954482672 Simplifying x = -25.954482672Solution
