Subproblem 1

Set the factor '(-21 + 21x + 2x2)' equal to zero and attempt to solve: Simplifying -21 + 21x + 2x2 = 0 Solving -21 + 21x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -10.5 + 10.5x + x2 = 0 Move the constant term to the right: Add '10.5' to each side of the equation. -10.5 + 10.5x + 10.5 + x2 = 0 + 10.5 Reorder the terms: -10.5 + 10.5 + 10.5x + x2 = 0 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + 10.5x + x2 = 0 + 10.5 10.5x + x2 = 0 + 10.5 Combine like terms: 0 + 10.5 = 10.5 10.5x + x2 = 10.5 The x term is 10.5x. Take half its coefficient (5.25). Square it (27.5625) and add it to both sides. Add '27.5625' to each side of the equation. 10.5x + 27.5625 + x2 = 10.5 + 27.5625 Reorder the terms: 27.5625 + 10.5x + x2 = 10.5 + 27.5625 Combine like terms: 10.5 + 27.5625 = 38.0625 27.5625 + 10.5x + x2 = 38.0625 Factor a perfect square on the left side: (x + 5.25)(x + 5.25) = 38.0625 Calculate the square root of the right side: 6.16948134 Break this problem into two subproblems by setting (x + 5.25) equal to 6.16948134 and -6.16948134.
