Simplifying x = 4x2 + 6x + -16 Reorder the terms: x = -16 + 6x + 4x2 Solving x = -16 + 6x + 4x2 Solving for variable 'x'. Reorder the terms: 16 + x + -6x + -4x2 = -16 + 6x + 4x2 + 16 + -6x + -4x2 Combine like terms: x + -6x = -5x 16 + -5x + -4x2 = -16 + 6x + 4x2 + 16 + -6x + -4x2 Reorder the terms: 16 + -5x + -4x2 = -16 + 16 + 6x + -6x + 4x2 + -4x2 Combine like terms: -16 + 16 = 0 16 + -5x + -4x2 = 0 + 6x + -6x + 4x2 + -4x2 16 + -5x + -4x2 = 6x + -6x + 4x2 + -4x2 Combine like terms: 6x + -6x = 0 16 + -5x + -4x2 = 0 + 4x2 + -4x2 16 + -5x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 16 + -5x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -4 + 1.25x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + 1.25x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 1.25x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 1.25x + x2 = 0 + 4 1.25x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 1.25x + x2 = 4 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 = 4 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = 4 + 0.390625 Combine like terms: 4 + 0.390625 = 4.390625 0.390625 + 1.25x + x2 = 4.390625 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = 4.390625 Calculate the square root of the right side: 2.095381827 Break this problem into two subproblems by setting (x + 0.625) equal to 2.095381827 and -2.095381827.Subproblem 1
x + 0.625 = 2.095381827 Simplifying x + 0.625 = 2.095381827 Reorder the terms: 0.625 + x = 2.095381827 Solving 0.625 + x = 2.095381827 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 = 2.095381827 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = 2.095381827 + -0.625 x = 2.095381827 + -0.625 Combine like terms: 2.095381827 + -0.625 = 1.470381827 x = 1.470381827 Simplifying x = 1.470381827Subproblem 2
x + 0.625 = -2.095381827 Simplifying x + 0.625 = -2.095381827 Reorder the terms: 0.625 + x = -2.095381827 Solving 0.625 + x = -2.095381827 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 = -2.095381827 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + x = -2.095381827 + -0.625 x = -2.095381827 + -0.625 Combine like terms: -2.095381827 + -0.625 = -2.720381827 x = -2.720381827 Simplifying x = -2.720381827Solution
