Simplifying 12 + -1 + -1x = 4x2 + 8x Combine like terms: 12 + -1 = 11 11 + -1x = 4x2 + 8x Reorder the terms: 11 + -1x = 8x + 4x2 Solving 11 + -1x = 8x + 4x2 Solving for variable 'x'. Combine like terms: -1x + -8x = -9x 11 + -9x + -4x2 = 8x + 4x2 + -8x + -4x2 Reorder the terms: 11 + -9x + -4x2 = 8x + -8x + 4x2 + -4x2 Combine like terms: 8x + -8x = 0 11 + -9x + -4x2 = 0 + 4x2 + -4x2 11 + -9x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 11 + -9x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -2.75 + 2.25x + x2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + 2.25x + 2.75 + x2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + 2.25x + x2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + 2.25x + x2 = 0 + 2.75 2.25x + x2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 2.25x + x2 = 2.75 The x term is 2.25x. Take half its coefficient (1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. 2.25x + 1.265625 + x2 = 2.75 + 1.265625 Reorder the terms: 1.265625 + 2.25x + x2 = 2.75 + 1.265625 Combine like terms: 2.75 + 1.265625 = 4.015625 1.265625 + 2.25x + x2 = 4.015625 Factor a perfect square on the left side: (x + 1.125)(x + 1.125) = 4.015625 Calculate the square root of the right side: 2.003902443 Break this problem into two subproblems by setting (x + 1.125) equal to 2.003902443 and -2.003902443.Subproblem 1
x + 1.125 = 2.003902443 Simplifying x + 1.125 = 2.003902443 Reorder the terms: 1.125 + x = 2.003902443 Solving 1.125 + x = 2.003902443 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = 2.003902443 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = 2.003902443 + -1.125 x = 2.003902443 + -1.125 Combine like terms: 2.003902443 + -1.125 = 0.878902443 x = 0.878902443 Simplifying x = 0.878902443Subproblem 2
x + 1.125 = -2.003902443 Simplifying x + 1.125 = -2.003902443 Reorder the terms: 1.125 + x = -2.003902443 Solving 1.125 + x = -2.003902443 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = -2.003902443 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = -2.003902443 + -1.125 x = -2.003902443 + -1.125 Combine like terms: -2.003902443 + -1.125 = -3.128902443 x = -3.128902443 Simplifying x = -3.128902443Solution
