Subproblem 1

Set the factor '(1 + -10x + x2)' equal to zero and attempt to solve: Simplifying 1 + -10x + x2 = 0 Solving 1 + -10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -10x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -10x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -10x + x2 = 0 + -1 -10x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -10x + x2 = -1 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = -1 + 25 Reorder the terms: 25 + -10x + x2 = -1 + 25 Combine like terms: -1 + 25 = 24 25 + -10x + x2 = 24 Factor a perfect square on the left side: (x + -5)(x + -5) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (x + -5) equal to 4.898979486 and -4.898979486.
