Subproblem 1

Set the factor '(-26 + 5x + -10x2)' equal to zero and attempt to solve: Simplifying -26 + 5x + -10x2 = 0 Solving -26 + 5x + -10x2 = 0 Begin completing the square. Divide all terms by -10 the coefficient of the squared term: Divide each side by '-10'. 2.6 + -0.5x + x2 = 0.0 Move the constant term to the right: Add '-2.6' to each side of the equation. 2.6 + -0.5x + -2.6 + x2 = 0.0 + -2.6 Reorder the terms: 2.6 + -2.6 + -0.5x + x2 = 0.0 + -2.6 Combine like terms: 2.6 + -2.6 = 0.0 0.0 + -0.5x + x2 = 0.0 + -2.6 -0.5x + x2 = 0.0 + -2.6 Combine like terms: 0.0 + -2.6 = -2.6 -0.5x + x2 = -2.6 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 = -2.6 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -2.6 + 0.0625 Combine like terms: -2.6 + 0.0625 = -2.5375 0.0625 + -0.5x + x2 = -2.5375 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -2.5375 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.
