Subproblem 1

Set the factor '(5 + -20x + 2x2)' equal to zero and attempt to solve: Simplifying 5 + -20x + 2x2 = 0 Solving 5 + -20x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + -10x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -10x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -10x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -10x + x2 = 0 + -2.5 -10x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -10x + x2 = -2.5 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 = -2.5 + 25 Reorder the terms: 25 + -10x + x2 = -2.5 + 25 Combine like terms: -2.5 + 25 = 22.5 25 + -10x + x2 = 22.5 Factor a perfect square on the left side: (x + -5)(x + -5) = 22.5 Calculate the square root of the right side: 4.74341649 Break this problem into two subproblems by setting (x + -5) equal to 4.74341649 and -4.74341649.
