Simplifying a2 + 3 = 3a + 9 Reorder the terms: 3 + a2 = 3a + 9 Reorder the terms: 3 + a2 = 9 + 3a Solving 3 + a2 = 9 + 3a Solving for variable 'a'. Reorder the terms: 3 + -9 + -3a + a2 = 9 + 3a + -9 + -3a Combine like terms: 3 + -9 = -6 -6 + -3a + a2 = 9 + 3a + -9 + -3a Reorder the terms: -6 + -3a + a2 = 9 + -9 + 3a + -3a Combine like terms: 9 + -9 = 0 -6 + -3a + a2 = 0 + 3a + -3a -6 + -3a + a2 = 3a + -3a Combine like terms: 3a + -3a = 0 -6 + -3a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + -3a + 6 + a2 = 0 + 6 Reorder the terms: -6 + 6 + -3a + a2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -3a + a2 = 0 + 6 -3a + a2 = 0 + 6 Combine like terms: 0 + 6 = 6 -3a + a2 = 6 The a term is -3a. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3a + 2.25 + a2 = 6 + 2.25 Reorder the terms: 2.25 + -3a + a2 = 6 + 2.25 Combine like terms: 6 + 2.25 = 8.25 2.25 + -3a + a2 = 8.25 Factor a perfect square on the left side: (a + -1.5)(a + -1.5) = 8.25 Calculate the square root of the right side: 2.872281323 Break this problem into two subproblems by setting (a + -1.5) equal to 2.872281323 and -2.872281323.Subproblem 1
a + -1.5 = 2.872281323 Simplifying a + -1.5 = 2.872281323 Reorder the terms: -1.5 + a = 2.872281323 Solving -1.5 + a = 2.872281323 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + a = 2.872281323 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + a = 2.872281323 + 1.5 a = 2.872281323 + 1.5 Combine like terms: 2.872281323 + 1.5 = 4.372281323 a = 4.372281323 Simplifying a = 4.372281323Subproblem 2
a + -1.5 = -2.872281323 Simplifying a + -1.5 = -2.872281323 Reorder the terms: -1.5 + a = -2.872281323 Solving -1.5 + a = -2.872281323 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + a = -2.872281323 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + a = -2.872281323 + 1.5 a = -2.872281323 + 1.5 Combine like terms: -2.872281323 + 1.5 = -1.372281323 a = -1.372281323 Simplifying a = -1.372281323Solution
The solution to the problem is based on the solutions from the subproblems. a = {4.372281323, -1.372281323}
