Simplifying 2x2 + 5x + -38 = 0 Reorder the terms: -38 + 5x + 2x2 = 0 Solving -38 + 5x + 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'. -19 + 2.5x + x2 = 0 Move the constant term to the right: Add '19' to each side of the equation. -19 + 2.5x + 19 + x2 = 0 + 19 Reorder the terms: -19 + 19 + 2.5x + x2 = 0 + 19 Combine like terms: -19 + 19 = 0 0 + 2.5x + x2 = 0 + 19 2.5x + x2 = 0 + 19 Combine like terms: 0 + 19 = 19 2.5x + x2 = 19 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 19 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 19 + 1.5625 Combine like terms: 19 + 1.5625 = 20.5625 1.5625 + 2.5x + x2 = 20.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 20.5625 Calculate the square root of the right side: 4.534589287 Break this problem into two subproblems by setting (x + 1.25) equal to 4.534589287 and -4.534589287.Subproblem 1
x + 1.25 = 4.534589287 Simplifying x + 1.25 = 4.534589287 Reorder the terms: 1.25 + x = 4.534589287 Solving 1.25 + x = 4.534589287 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 4.534589287 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 4.534589287 + -1.25 x = 4.534589287 + -1.25 Combine like terms: 4.534589287 + -1.25 = 3.284589287 x = 3.284589287 Simplifying x = 3.284589287Subproblem 2
x + 1.25 = -4.534589287 Simplifying x + 1.25 = -4.534589287 Reorder the terms: 1.25 + x = -4.534589287 Solving 1.25 + x = -4.534589287 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -4.534589287 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -4.534589287 + -1.25 x = -4.534589287 + -1.25 Combine like terms: -4.534589287 + -1.25 = -5.784589287 x = -5.784589287 Simplifying x = -5.784589287Solution
