Subproblem 1

Set the factor '(4 + 7a + 4a2)' equal to zero and attempt to solve: Simplifying 4 + 7a + 4a2 = 0 Solving 4 + 7a + 4a2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1 + 1.75a + a2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 1.75a + -1 + a2 = 0 + -1 Reorder the terms: 1 + -1 + 1.75a + a2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 1.75a + a2 = 0 + -1 1.75a + a2 = 0 + -1 Combine like terms: 0 + -1 = -1 1.75a + a2 = -1 The a term is 1.75a. Take half its coefficient (0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. 1.75a + 0.765625 + a2 = -1 + 0.765625 Reorder the terms: 0.765625 + 1.75a + a2 = -1 + 0.765625 Combine like terms: -1 + 0.765625 = -0.234375 0.765625 + 1.75a + a2 = -0.234375 Factor a perfect square on the left side: (a + 0.875)(a + 0.875) = -0.234375 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.
