Subproblem 1

Set the factor '(-60 + 3x + x2)' equal to zero and attempt to solve: Simplifying -60 + 3x + x2 = 0 Solving -60 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '60' to each side of the equation. -60 + 3x + 60 + x2 = 0 + 60 Reorder the terms: -60 + 60 + 3x + x2 = 0 + 60 Combine like terms: -60 + 60 = 0 0 + 3x + x2 = 0 + 60 3x + x2 = 0 + 60 Combine like terms: 0 + 60 = 60 3x + x2 = 60 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 60 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 60 + 2.25 Combine like terms: 60 + 2.25 = 62.25 2.25 + 3x + x2 = 62.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 62.25 Calculate the square root of the right side: 7.889866919 Break this problem into two subproblems by setting (x + 1.5) equal to 7.889866919 and -7.889866919.
