Simplifying a2 = 28 + -3a + -1a2 Solving a2 = 28 + -3a + -1a2 Solving for variable 'a'. Reorder the terms: -28 + 3a + a2 + a2 = 28 + -3a + -1a2 + -28 + 3a + a2 Combine like terms: a2 + a2 = 2a2 -28 + 3a + 2a2 = 28 + -3a + -1a2 + -28 + 3a + a2 Reorder the terms: -28 + 3a + 2a2 = 28 + -28 + -3a + 3a + -1a2 + a2 Combine like terms: 28 + -28 = 0 -28 + 3a + 2a2 = 0 + -3a + 3a + -1a2 + a2 -28 + 3a + 2a2 = -3a + 3a + -1a2 + a2 Combine like terms: -3a + 3a = 0 -28 + 3a + 2a2 = 0 + -1a2 + a2 -28 + 3a + 2a2 = -1a2 + a2 Combine like terms: -1a2 + a2 = 0 -28 + 3a + 2a2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -14 + 1.5a + a2 = 0 Move the constant term to the right: Add '14' to each side of the equation. -14 + 1.5a + 14 + a2 = 0 + 14 Reorder the terms: -14 + 14 + 1.5a + a2 = 0 + 14 Combine like terms: -14 + 14 = 0 0 + 1.5a + a2 = 0 + 14 1.5a + a2 = 0 + 14 Combine like terms: 0 + 14 = 14 1.5a + a2 = 14 The a term is 1.5a. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5a + 0.5625 + a2 = 14 + 0.5625 Reorder the terms: 0.5625 + 1.5a + a2 = 14 + 0.5625 Combine like terms: 14 + 0.5625 = 14.5625 0.5625 + 1.5a + a2 = 14.5625 Factor a perfect square on the left side: (a + 0.75)(a + 0.75) = 14.5625 Calculate the square root of the right side: 3.816084381 Break this problem into two subproblems by setting (a + 0.75) equal to 3.816084381 and -3.816084381.Subproblem 1
a + 0.75 = 3.816084381 Simplifying a + 0.75 = 3.816084381 Reorder the terms: 0.75 + a = 3.816084381 Solving 0.75 + a = 3.816084381 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + a = 3.816084381 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + a = 3.816084381 + -0.75 a = 3.816084381 + -0.75 Combine like terms: 3.816084381 + -0.75 = 3.066084381 a = 3.066084381 Simplifying a = 3.066084381Subproblem 2
a + 0.75 = -3.816084381 Simplifying a + 0.75 = -3.816084381 Reorder the terms: 0.75 + a = -3.816084381 Solving 0.75 + a = -3.816084381 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + a = -3.816084381 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + a = -3.816084381 + -0.75 a = -3.816084381 + -0.75 Combine like terms: -3.816084381 + -0.75 = -4.566084381 a = -4.566084381 Simplifying a = -4.566084381Solution
