Simplifying 8a2 + -9a + -9 = 4 + -3a Reorder the terms: -9 + -9a + 8a2 = 4 + -3a Solving -9 + -9a + 8a2 = 4 + -3a Solving for variable 'a'. Reorder the terms: -9 + -4 + -9a + 3a + 8a2 = 4 + -3a + -4 + 3a Combine like terms: -9 + -4 = -13 -13 + -9a + 3a + 8a2 = 4 + -3a + -4 + 3a Combine like terms: -9a + 3a = -6a -13 + -6a + 8a2 = 4 + -3a + -4 + 3a Reorder the terms: -13 + -6a + 8a2 = 4 + -4 + -3a + 3a Combine like terms: 4 + -4 = 0 -13 + -6a + 8a2 = 0 + -3a + 3a -13 + -6a + 8a2 = -3a + 3a Combine like terms: -3a + 3a = 0 -13 + -6a + 8a2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -1.625 + -0.75a + a2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + -0.75a + 1.625 + a2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + -0.75a + a2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + -0.75a + a2 = 0 + 1.625 -0.75a + a2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 -0.75a + a2 = 1.625 The a term is -0.75a. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75a + 0.140625 + a2 = 1.625 + 0.140625 Reorder the terms: 0.140625 + -0.75a + a2 = 1.625 + 0.140625 Combine like terms: 1.625 + 0.140625 = 1.765625 0.140625 + -0.75a + a2 = 1.765625 Factor a perfect square on the left side: (a + -0.375)(a + -0.375) = 1.765625 Calculate the square root of the right side: 1.328768227 Break this problem into two subproblems by setting (a + -0.375) equal to 1.328768227 and -1.328768227.Subproblem 1
a + -0.375 = 1.328768227 Simplifying a + -0.375 = 1.328768227 Reorder the terms: -0.375 + a = 1.328768227 Solving -0.375 + a = 1.328768227 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + a = 1.328768227 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + a = 1.328768227 + 0.375 a = 1.328768227 + 0.375 Combine like terms: 1.328768227 + 0.375 = 1.703768227 a = 1.703768227 Simplifying a = 1.703768227Subproblem 2
a + -0.375 = -1.328768227 Simplifying a + -0.375 = -1.328768227 Reorder the terms: -0.375 + a = -1.328768227 Solving -0.375 + a = -1.328768227 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + a = -1.328768227 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + a = -1.328768227 + 0.375 a = -1.328768227 + 0.375 Combine like terms: -1.328768227 + 0.375 = -0.953768227 a = -0.953768227 Simplifying a = -0.953768227Solution
