Simplifying 2x2 + 2x + -1.5 = 0 Reorder the terms: -1.5 + 2x + 2x2 = 0 Solving -1.5 + 2x + 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'. -0.75 + x + x2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + x + 0.75 + x2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + x + x2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x + x2 = 0 + 0.75 x + x2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 x + x2 = 0.75 The x term is x. 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. + 0.25 + x2 = 0.75 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 0.75 + 0.25 Combine like terms: 0.75 + 0.25 = 1 1.25 + x2 = 1 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 1 Calculate the square root of the right side: 1 Break this problem into two subproblems by setting (x + 0.5) equal to 1 and -1.Subproblem 1
x + 0.5 = 1 Simplifying x + 0.5 = 1 Reorder the terms: 0.5 + x = 1 Solving 0.5 + x = 1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 1 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1 + -0.5 x = 1 + -0.5 Combine like terms: 1 + -0.5 = 0.5 x = 0.5 Simplifying x = 0.5Subproblem 2
x + 0.5 = -1 Simplifying x + 0.5 = -1 Reorder the terms: 0.5 + x = -1 Solving 0.5 + x = -1 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -1 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1 + -0.5 x = -1 + -0.5 Combine like terms: -1 + -0.5 = -1.5 x = -1.5 Simplifying x = -1.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.5, -1.5}
