Simplifying 2x2 + 7x + -2 = -2x2 + 2x Reorder the terms: -2 + 7x + 2x2 = -2x2 + 2x Reorder the terms: -2 + 7x + 2x2 = 2x + -2x2 Solving -2 + 7x + 2x2 = 2x + -2x2 Solving for variable 'x'. Reorder the terms: -2 + 7x + -2x + 2x2 + 2x2 = 2x + -2x2 + -2x + 2x2 Combine like terms: 7x + -2x = 5x -2 + 5x + 2x2 + 2x2 = 2x + -2x2 + -2x + 2x2 Combine like terms: 2x2 + 2x2 = 4x2 -2 + 5x + 4x2 = 2x + -2x2 + -2x + 2x2 Reorder the terms: -2 + 5x + 4x2 = 2x + -2x + -2x2 + 2x2 Combine like terms: 2x + -2x = 0 -2 + 5x + 4x2 = 0 + -2x2 + 2x2 -2 + 5x + 4x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 -2 + 5x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.5 + 1.25x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 1.25x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 1.25x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 1.25x + x2 = 0 + 0.5 1.25x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 1.25x + x2 = 0.5 The x term is 1.25x. Take half its coefficient (0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. 1.25x + 0.390625 + x2 = 0.5 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = 0.5 + 0.390625 Combine like terms: 0.5 + 0.390625 = 0.890625 0.390625 + 1.25x + x2 = 0.890625 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = 0.890625 Calculate the square root of the right side: 0.943729304 Break this problem into two subproblems by setting (x + 0.625) equal to 0.943729304 and -0.943729304.Subproblem 1
x + 0.625 = 0.943729304 Simplifying x + 0.625 = 0.943729304 Reorder the terms: 0.625 + x = 0.943729304 Solving 0.625 + x = 0.943729304 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.625' to each side of the equation. 0.625 + -0.625 + x = 0.943729304 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = 0.943729304 + -0.625 x = 0.943729304 + -0.625 Combine like terms: 0.943729304 + -0.625 = 0.318729304 x = 0.318729304 Simplifying x = 0.318729304Subproblem 2
x + 0.625 = -0.943729304 Simplifying x + 0.625 = -0.943729304 Reorder the terms: 0.625 + x = -0.943729304 Solving 0.625 + x = -0.943729304 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.625' to each side of the equation. 0.625 + -0.625 + x = -0.943729304 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = -0.943729304 + -0.625 x = -0.943729304 + -0.625 Combine like terms: -0.943729304 + -0.625 = -1.568729304 x = -1.568729304 Simplifying x = -1.568729304Solution
