Subproblem 1

Set the factor '(-34 + -6x + x2)' equal to zero and attempt to solve: Simplifying -34 + -6x + x2 = 0 Solving -34 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '34' to each side of the equation. -34 + -6x + 34 + x2 = 0 + 34 Reorder the terms: -34 + 34 + -6x + x2 = 0 + 34 Combine like terms: -34 + 34 = 0 0 + -6x + x2 = 0 + 34 -6x + x2 = 0 + 34 Combine like terms: 0 + 34 = 34 -6x + x2 = 34 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 34 + 9 Reorder the terms: 9 + -6x + x2 = 34 + 9 Combine like terms: 34 + 9 = 43 9 + -6x + x2 = 43 Factor a perfect square on the left side: (x + -3)(x + -3) = 43 Calculate the square root of the right side: 6.557438524 Break this problem into two subproblems by setting (x + -3) equal to 6.557438524 and -6.557438524.
