Subproblem 1

Set the factor '(-7 + 3x + x2)' equal to zero and attempt to solve: Simplifying -7 + 3x + x2 = 0 Solving -7 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + 3x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + 3x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 3x + x2 = 0 + 7 3x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 3x + x2 = 7 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 = 7 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 7 + 2.25 Combine like terms: 7 + 2.25 = 9.25 2.25 + 3x + x2 = 9.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + 1.5) equal to 3.041381265 and -3.041381265.
