Simplifying 5.2 = -2x2 + 6x + 1 Reorder the terms: 5.2 = 1 + 6x + -2x2 Solving 5.2 = 1 + 6x + -2x2 Solving for variable 'x'. Combine like terms: 5.2 + -1 = 4.2 4.2 + -6x + 2x2 = 1 + 6x + -2x2 + -1 + -6x + 2x2 Reorder the terms: 4.2 + -6x + 2x2 = 1 + -1 + 6x + -6x + -2x2 + 2x2 Combine like terms: 1 + -1 = 0 4.2 + -6x + 2x2 = 0 + 6x + -6x + -2x2 + 2x2 4.2 + -6x + 2x2 = 6x + -6x + -2x2 + 2x2 Combine like terms: 6x + -6x = 0 4.2 + -6x + 2x2 = 0 + -2x2 + 2x2 4.2 + -6x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 4.2 + -6x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.1 + -3x + x2 = 0 Move the constant term to the right: Add '-2.1' to each side of the equation. 2.1 + -3x + -2.1 + x2 = 0 + -2.1 Reorder the terms: 2.1 + -2.1 + -3x + x2 = 0 + -2.1 Combine like terms: 2.1 + -2.1 = 0.0 0.0 + -3x + x2 = 0 + -2.1 -3x + x2 = 0 + -2.1 Combine like terms: 0 + -2.1 = -2.1 -3x + x2 = -2.1 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 = -2.1 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -2.1 + 2.25 Combine like terms: -2.1 + 2.25 = 0.15 2.25 + -3x + x2 = 0.15 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 0.15 Calculate the square root of the right side: 0.387298335 Break this problem into two subproblems by setting (x + -1.5) equal to 0.387298335 and -0.387298335.Subproblem 1
x + -1.5 = 0.387298335 Simplifying x + -1.5 = 0.387298335 Reorder the terms: -1.5 + x = 0.387298335 Solving -1.5 + x = 0.387298335 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 = 0.387298335 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 0.387298335 + 1.5 x = 0.387298335 + 1.5 Combine like terms: 0.387298335 + 1.5 = 1.887298335 x = 1.887298335 Simplifying x = 1.887298335Subproblem 2
x + -1.5 = -0.387298335 Simplifying x + -1.5 = -0.387298335 Reorder the terms: -1.5 + x = -0.387298335 Solving -1.5 + x = -0.387298335 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 = -0.387298335 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -0.387298335 + 1.5 x = -0.387298335 + 1.5 Combine like terms: -0.387298335 + 1.5 = 1.112701665 x = 1.112701665 Simplifying x = 1.112701665Solution
