Set the factor '(27 + -28x2 + 28x4)' equal to zero and attempt to solve: Simplifying 27 + -28x2 + 28x4 = 0 Solving 27 + -28x2 + 28x4 = 0 Begin completing the square. Divide all terms by 28 the coefficient of the squared term: Divide each side by '28'. 0.9642857143 + -1x2 + x4 = 0 Move the constant term to the right: Add '-0.9642857143' to each side of the equation. 0.9642857143 + -1x2 + -0.9642857143 + x4 = 0 + -0.9642857143 Reorder the terms: 0.9642857143 + -0.9642857143 + -1x2 + x4 = 0 + -0.9642857143 Combine like terms: 0.9642857143 + -0.9642857143 = 0.0000000000 0.0000000000 + -1x2 + x4 = 0 + -0.9642857143 -1x2 + x4 = 0 + -0.9642857143 Combine like terms: 0 + -0.9642857143 = -0.9642857143 -1x2 + x4 = -0.9642857143 The x term is -1x2. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x2 + 0.25 + x4 = -0.9642857143 + 0.25 Reorder the terms: 0.25 + -1x2 + x4 = -0.9642857143 + 0.25 Combine like terms: -0.9642857143 + 0.25 = -0.7142857143 0.25 + -1x2 + x4 = -0.7142857143 Factor a perfect square on the left side: (x2 + -0.5)(x2 + -0.5) = -0.7142857143 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
