Simplifying -0.5x2 + 1.5x + 2 = 1.68 Reorder the terms: 2 + 1.5x + -0.5x2 = 1.68 Solving 2 + 1.5x + -0.5x2 = 1.68 Solving for variable 'x'. Reorder the terms: 2 + -1.68 + 1.5x + -0.5x2 = 1.68 + -1.68 Combine like terms: 2 + -1.68 = 0.32 0.32 + 1.5x + -0.5x2 = 1.68 + -1.68 Combine like terms: 1.68 + -1.68 = 0.00 0.32 + 1.5x + -0.5x2 = 0.00 Begin completing the square. Divide all terms by -0.5 the coefficient of the squared term: Divide each side by '-0.5'. -0.64 + -3x + x2 = 0.0 Move the constant term to the right: Add '0.64' to each side of the equation. -0.64 + -3x + 0.64 + x2 = 0.0 + 0.64 Reorder the terms: -0.64 + 0.64 + -3x + x2 = 0.0 + 0.64 Combine like terms: -0.64 + 0.64 = 0.00 0.00 + -3x + x2 = 0.0 + 0.64 -3x + x2 = 0.0 + 0.64 Combine like terms: 0.0 + 0.64 = 0.64 -3x + x2 = 0.64 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 = 0.64 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 0.64 + 2.25 Combine like terms: 0.64 + 2.25 = 2.89 2.25 + -3x + x2 = 2.89 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 2.89 Calculate the square root of the right side: 1.7 Break this problem into two subproblems by setting (x + -1.5) equal to 1.7 and -1.7.Subproblem 1
x + -1.5 = 1.7 Simplifying x + -1.5 = 1.7 Reorder the terms: -1.5 + x = 1.7 Solving -1.5 + x = 1.7 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 = 1.7 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 1.7 + 1.5 x = 1.7 + 1.5 Combine like terms: 1.7 + 1.5 = 3.2 x = 3.2 Simplifying x = 3.2Subproblem 2
x + -1.5 = -1.7 Simplifying x + -1.5 = -1.7 Reorder the terms: -1.5 + x = -1.7 Solving -1.5 + x = -1.7 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 = -1.7 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -1.7 + 1.5 x = -1.7 + 1.5 Combine like terms: -1.7 + 1.5 = -0.2 x = -0.2 Simplifying x = -0.2Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.2, -0.2}
