Subproblem 1

Set the factor '(9 + -2a + 5a2)' equal to zero and attempt to solve: Simplifying 9 + -2a + 5a2 = 0 Solving 9 + -2a + 5a2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.8 + -0.4a + a2 = 0 Move the constant term to the right: Add '-1.8' to each side of the equation. 1.8 + -0.4a + -1.8 + a2 = 0 + -1.8 Reorder the terms: 1.8 + -1.8 + -0.4a + a2 = 0 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + -0.4a + a2 = 0 + -1.8 -0.4a + a2 = 0 + -1.8 Combine like terms: 0 + -1.8 = -1.8 -0.4a + a2 = -1.8 The a term is -0.4a. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4a + 0.04 + a2 = -1.8 + 0.04 Reorder the terms: 0.04 + -0.4a + a2 = -1.8 + 0.04 Combine like terms: -1.8 + 0.04 = -1.76 0.04 + -0.4a + a2 = -1.76 Factor a perfect square on the left side: (a + -0.2)(a + -0.2) = -1.76 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.
