Simplifying a2 + -1a + -24 = 0 Reorder the terms: -24 + -1a + a2 = 0 Solving -24 + -1a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '24' to each side of the equation. -24 + -1a + 24 + a2 = 0 + 24 Reorder the terms: -24 + 24 + -1a + a2 = 0 + 24 Combine like terms: -24 + 24 = 0 0 + -1a + a2 = 0 + 24 -1a + a2 = 0 + 24 Combine like terms: 0 + 24 = 24 -1a + a2 = 24 The a term is -1a. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1a + 0.25 + a2 = 24 + 0.25 Reorder the terms: 0.25 + -1a + a2 = 24 + 0.25 Combine like terms: 24 + 0.25 = 24.25 0.25 + -1a + a2 = 24.25 Factor a perfect square on the left side: (a + -0.5)(a + -0.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (a + -0.5) equal to 4.924428901 and -4.924428901.Subproblem 1
a + -0.5 = 4.924428901 Simplifying a + -0.5 = 4.924428901 Reorder the terms: -0.5 + a = 4.924428901 Solving -0.5 + a = 4.924428901 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + a = 4.924428901 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + a = 4.924428901 + 0.5 a = 4.924428901 + 0.5 Combine like terms: 4.924428901 + 0.5 = 5.424428901 a = 5.424428901 Simplifying a = 5.424428901Subproblem 2
a + -0.5 = -4.924428901 Simplifying a + -0.5 = -4.924428901 Reorder the terms: -0.5 + a = -4.924428901 Solving -0.5 + a = -4.924428901 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + a = -4.924428901 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + a = -4.924428901 + 0.5 a = -4.924428901 + 0.5 Combine like terms: -4.924428901 + 0.5 = -4.424428901 a = -4.424428901 Simplifying a = -4.424428901Solution
The solution to the problem is based on the solutions from the subproblems. a = {5.424428901, -4.424428901}
