Simplifying 2x2 + 6x + 2.5 = 0 Reorder the terms: 2.5 + 6x + 2x2 = 0 Solving 2.5 + 6x + 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'. 1.25 + 3x + x2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + 3x + -1.25 + x2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + 3x + x2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + 3x + x2 = 0 + -1.25 3x + x2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 3x + x2 = -1.25 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = -1.25 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -1.25 + 2.25 Combine like terms: -1.25 + 2.25 = 1 2.25 + 3x + x2 = 1 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 1 Calculate the square root of the right side: 1 Break this problem into two subproblems by setting (x + 1.5) equal to 1 and -1.Subproblem 1
x + 1.5 = 1 Simplifying x + 1.5 = 1 Reorder the terms: 1.5 + x = 1 Solving 1.5 + x = 1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 1 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 1 + -1.5 x = 1 + -1.5 Combine like terms: 1 + -1.5 = -0.5 x = -0.5 Simplifying x = -0.5Subproblem 2
x + 1.5 = -1 Simplifying x + 1.5 = -1 Reorder the terms: 1.5 + x = -1 Solving 1.5 + x = -1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -1 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -1 + -1.5 x = -1 + -1.5 Combine like terms: -1 + -1.5 = -2.5 x = -2.5 Simplifying x = -2.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.5, -2.5}
