Subproblem 1

Set the factor '(164 + 21x + -1x2)' equal to zero and attempt to solve: Simplifying 164 + 21x + -1x2 = 0 Solving 164 + 21x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -164 + -21x + x2 = 0 Move the constant term to the right: Add '164' to each side of the equation. -164 + -21x + 164 + x2 = 0 + 164 Reorder the terms: -164 + 164 + -21x + x2 = 0 + 164 Combine like terms: -164 + 164 = 0 0 + -21x + x2 = 0 + 164 -21x + x2 = 0 + 164 Combine like terms: 0 + 164 = 164 -21x + x2 = 164 The x term is -21x. Take half its coefficient (-10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. -21x + 110.25 + x2 = 164 + 110.25 Reorder the terms: 110.25 + -21x + x2 = 164 + 110.25 Combine like terms: 164 + 110.25 = 274.25 110.25 + -21x + x2 = 274.25 Factor a perfect square on the left side: (x + -10.5)(x + -10.5) = 274.25 Calculate the square root of the right side: 16.560495162 Break this problem into two subproblems by setting (x + -10.5) equal to 16.560495162 and -16.560495162.
