Simplifying -6x2 + 8 + -5 + 3x + 2x + -4x2 = 0 Reorder the terms: 8 + -5 + 3x + 2x + -6x2 + -4x2 = 0 Combine like terms: 8 + -5 = 3 3 + 3x + 2x + -6x2 + -4x2 = 0 Combine like terms: 3x + 2x = 5x 3 + 5x + -6x2 + -4x2 = 0 Combine like terms: -6x2 + -4x2 = -10x2 3 + 5x + -10x2 = 0 Solving 3 + 5x + -10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. -0.3 + -0.5x + x2 = 0.0 Move the constant term to the right: Add '0.3' to each side of the equation. -0.3 + -0.5x + 0.3 + x2 = 0.0 + 0.3 Reorder the terms: -0.3 + 0.3 + -0.5x + x2 = 0.0 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + -0.5x + x2 = 0.0 + 0.3 -0.5x + x2 = 0.0 + 0.3 Combine like terms: 0.0 + 0.3 = 0.3 -0.5x + x2 = 0.3 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 0.3 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 0.3 + 0.0625 Combine like terms: 0.3 + 0.0625 = 0.3625 0.0625 + -0.5x + x2 = 0.3625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 0.3625 Calculate the square root of the right side: 0.602079729 Break this problem into two subproblems by setting (x + -0.25) equal to 0.602079729 and -0.602079729.Subproblem 1
x + -0.25 = 0.602079729 Simplifying x + -0.25 = 0.602079729 Reorder the terms: -0.25 + x = 0.602079729 Solving -0.25 + x = 0.602079729 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 0.602079729 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 0.602079729 + 0.25 x = 0.602079729 + 0.25 Combine like terms: 0.602079729 + 0.25 = 0.852079729 x = 0.852079729 Simplifying x = 0.852079729Subproblem 2
x + -0.25 = -0.602079729 Simplifying x + -0.25 = -0.602079729 Reorder the terms: -0.25 + x = -0.602079729 Solving -0.25 + x = -0.602079729 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -0.602079729 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -0.602079729 + 0.25 x = -0.602079729 + 0.25 Combine like terms: -0.602079729 + 0.25 = -0.352079729 x = -0.352079729 Simplifying x = -0.352079729Solution
