Simplifying 3 + -4x + -2x2 = 0 Solving 3 + -4x + -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'. -1.5 + 2x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 2x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 2x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 2x + x2 = 0 + 1.5 2x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 2x + x2 = 1.5 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 1.5 + 1 Reorder the terms: 1 + 2x + x2 = 1.5 + 1 Combine like terms: 1.5 + 1 = 2.5 1 + 2x + x2 = 2.5 Factor a perfect square on the left side: (x + 1)(x + 1) = 2.5 Calculate the square root of the right side: 1.58113883 Break this problem into two subproblems by setting (x + 1) equal to 1.58113883 and -1.58113883.Subproblem 1
x + 1 = 1.58113883 Simplifying x + 1 = 1.58113883 Reorder the terms: 1 + x = 1.58113883 Solving 1 + x = 1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 1.58113883 + -1 Combine like terms: 1 + -1 = 0 0 + x = 1.58113883 + -1 x = 1.58113883 + -1 Combine like terms: 1.58113883 + -1 = 0.58113883 x = 0.58113883 Simplifying x = 0.58113883Subproblem 2
x + 1 = -1.58113883 Simplifying x + 1 = -1.58113883 Reorder the terms: 1 + x = -1.58113883 Solving 1 + x = -1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -1.58113883 + -1 Combine like terms: 1 + -1 = 0 0 + x = -1.58113883 + -1 x = -1.58113883 + -1 Combine like terms: -1.58113883 + -1 = -2.58113883 x = -2.58113883 Simplifying x = -2.58113883Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.58113883, -2.58113883}
