Subproblem 1

Set the factor '(-47 + 5x + 10x2)' equal to zero and attempt to solve: Simplifying -47 + 5x + 10x2 = 0 Solving -47 + 5x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -4.7 + 0.5x + x2 = 0.0 Move the constant term to the right: Add '4.7' to each side of the equation. -4.7 + 0.5x + 4.7 + x2 = 0.0 + 4.7 Reorder the terms: -4.7 + 4.7 + 0.5x + x2 = 0.0 + 4.7 Combine like terms: -4.7 + 4.7 = 0.0 0.0 + 0.5x + x2 = 0.0 + 4.7 0.5x + x2 = 0.0 + 4.7 Combine like terms: 0.0 + 4.7 = 4.7 0.5x + x2 = 4.7 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = 4.7 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = 4.7 + 0.0625 Combine like terms: 4.7 + 0.0625 = 4.7625 0.0625 + 0.5x + x2 = 4.7625 Factor a perfect square on the left side: (x + 0.25)(x + 0.25) = 4.7625 Calculate the square root of the right side: 2.182315284 Break this problem into two subproblems by setting (x + 0.25) equal to 2.182315284 and -2.182315284.
