Subproblem 1

Set the factor '(-17 + -9x + x2)' equal to zero and attempt to solve: Simplifying -17 + -9x + x2 = 0 Solving -17 + -9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '17' to each side of the equation. -17 + -9x + 17 + x2 = 0 + 17 Reorder the terms: -17 + 17 + -9x + x2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + -9x + x2 = 0 + 17 -9x + x2 = 0 + 17 Combine like terms: 0 + 17 = 17 -9x + x2 = 17 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = 17 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 17 + 20.25 Combine like terms: 17 + 20.25 = 37.25 20.25 + -9x + x2 = 37.25 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 37.25 Calculate the square root of the right side: 6.103277808 Break this problem into two subproblems by setting (x + -4.5) equal to 6.103277808 and -6.103277808.
