Subproblem 1

Set the factor '(-4 + 9a + -4a2)' equal to zero and attempt to solve: Simplifying -4 + 9a + -4a2 = 0 Solving -4 + 9a + -4a2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 1 + -2.25a + a2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + -2.25a + -1 + a2 = 0 + -1 Reorder the terms: 1 + -1 + -2.25a + a2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2.25a + a2 = 0 + -1 -2.25a + a2 = 0 + -1 Combine like terms: 0 + -1 = -1 -2.25a + a2 = -1 The a term is -2.25a. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25a + 1.265625 + a2 = -1 + 1.265625 Reorder the terms: 1.265625 + -2.25a + a2 = -1 + 1.265625 Combine like terms: -1 + 1.265625 = 0.265625 1.265625 + -2.25a + a2 = 0.265625 Factor a perfect square on the left side: (a + -1.125)(a + -1.125) = 0.265625 Calculate the square root of the right side: 0.515388203 Break this problem into two subproblems by setting (a + -1.125) equal to 0.515388203 and -0.515388203.

Subproblem 1

a + -1.125 = 0.515388203 Simplifying a + -1.125 = 0.515388203 Reorder the terms: -1.125 + a = 0.515388203 Solving -1.125 + a = 0.515388203 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + a = 0.515388203 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + a = 0.515388203 + 1.125 a = 0.515388203 + 1.125 Combine like terms: 0.515388203 + 1.125 = 1.640388203 a = 1.640388203 Simplifying a = 1.640388203

Subproblem 2

a + -1.125 = -0.515388203 Simplifying a + -1.125 = -0.515388203 Reorder the terms: -1.125 + a = -0.515388203 Solving -1.125 + a = -0.515388203 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + a = -0.515388203 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + a = -0.515388203 + 1.125 a = -0.515388203 + 1.125 Combine like terms: -0.515388203 + 1.125 = 0.609611797 a = 0.609611797 Simplifying a = 0.609611797
