Subproblem 1

Set the factor '(14 + -16x + x2)' equal to zero and attempt to solve: Simplifying 14 + -16x + x2 = 0 Solving 14 + -16x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-14' to each side of the equation. 14 + -16x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + -16x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + -16x + x2 = 0 + -14 -16x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 -16x + x2 = -14 The x term is -16x. Take half its coefficient (-8). Square it (64) and add it to both sides. Add '64' to each side of the equation. -16x + 64 + x2 = -14 + 64 Reorder the terms: 64 + -16x + x2 = -14 + 64 Combine like terms: -14 + 64 = 50 64 + -16x + x2 = 50 Factor a perfect square on the left side: (x + -8)(x + -8) = 50 Calculate the square root of the right side: 7.071067812 Break this problem into two subproblems by setting (x + -8) equal to 7.071067812 and -7.071067812.
