Subproblem 1

Set the factor '(14 + -9x + 2x2)' equal to zero and attempt to solve: Simplifying 14 + -9x + 2x2 = 0 Solving 14 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7 + -4.5x + x2 = 0 Move the constant term to the right: Add '-7' to each side of the equation. 7 + -4.5x + -7 + x2 = 0 + -7 Reorder the terms: 7 + -7 + -4.5x + x2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -4.5x + x2 = 0 + -7 -4.5x + x2 = 0 + -7 Combine like terms: 0 + -7 = -7 -4.5x + x2 = -7 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = -7 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = -7 + 5.0625 Combine like terms: -7 + 5.0625 = -1.9375 5.0625 + -4.5x + x2 = -1.9375 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = -1.9375 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.
