Subproblem 1

Set the factor '(5 + 3x + 5x2)' equal to zero and attempt to solve: Simplifying 5 + 3x + 5x2 = 0 Solving 5 + 3x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1 + 0.6x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 0.6x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + 0.6x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 0.6x + x2 = 0 + -1 0.6x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 0.6x + x2 = -1 The x term is 0.6x. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6x + 0.09 + x2 = -1 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = -1 + 0.09 Combine like terms: -1 + 0.09 = -0.91 0.09 + 0.6x + x2 = -0.91 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = -0.91 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
