Subproblem 1

Set the factor '(-12 + 2x + x2)' equal to zero and attempt to solve: Simplifying -12 + 2x + x2 = 0 Solving -12 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + 2x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 2x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 2x + x2 = 0 + 12 2x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 2x + x2 = 12 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 12 + 1 Reorder the terms: 1 + 2x + x2 = 12 + 1 Combine like terms: 12 + 1 = 13 1 + 2x + x2 = 13 Factor a perfect square on the left side: (x + 1)(x + 1) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (x + 1) equal to 3.605551275 and -3.605551275.
