Subproblem 1

Set the factor '(-30 + 3x + x2)' equal to zero and attempt to solve: Simplifying -30 + 3x + x2 = 0 Solving -30 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + 3x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + 3x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + 3x + x2 = 0 + 30 3x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 3x + x2 = 30 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 = 30 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 30 + 2.25 Combine like terms: 30 + 2.25 = 32.25 2.25 + 3x + x2 = 32.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 32.25 Calculate the square root of the right side: 5.678908346 Break this problem into two subproblems by setting (x + 1.5) equal to 5.678908346 and -5.678908346.
