Subproblem 1

Set the factor '(1 + 6x + 4x2)' equal to zero and attempt to solve: Simplifying 1 + 6x + 4x2 = 0 Solving 1 + 6x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.25 + 1.5x + x2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + 1.5x + -0.25 + x2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + 1.5x + x2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + 1.5x + x2 = 0 + -0.25 1.5x + x2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 1.5x + x2 = -0.25 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -0.25 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -0.25 + 0.5625 Combine like terms: -0.25 + 0.5625 = 0.3125 0.5625 + 1.5x + x2 = 0.3125 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 0.3125 Calculate the square root of the right side: 0.559016994 Break this problem into two subproblems by setting (x + 0.75) equal to 0.559016994 and -0.559016994.
