Subproblem 1

Set the factor '(6 + 16x + 5x2)' equal to zero and attempt to solve: Simplifying 6 + 16x + 5x2 = 0 Solving 6 + 16x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.2 + 3.2x + x2 = 0 Move the constant term to the right: Add '-1.2' to each side of the equation. 1.2 + 3.2x + -1.2 + x2 = 0 + -1.2 Reorder the terms: 1.2 + -1.2 + 3.2x + x2 = 0 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + 3.2x + x2 = 0 + -1.2 3.2x + x2 = 0 + -1.2 Combine like terms: 0 + -1.2 = -1.2 3.2x + x2 = -1.2 The x term is 3.2x. Take half its coefficient (1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. 3.2x + 2.56 + x2 = -1.2 + 2.56 Reorder the terms: 2.56 + 3.2x + x2 = -1.2 + 2.56 Combine like terms: -1.2 + 2.56 = 1.36 2.56 + 3.2x + x2 = 1.36 Factor a perfect square on the left side: (x + 1.6)(x + 1.6) = 1.36 Calculate the square root of the right side: 1.166190379 Break this problem into two subproblems by setting (x + 1.6) equal to 1.166190379 and -1.166190379.
