Simplifying 2a2 + a + -5 = 0 Reorder the terms: -5 + a + 2a2 = 0 Solving -5 + a + 2a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 0.5a + a2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 0.5a + 2.5 + a2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 0.5a + a2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 0.5a + a2 = 0 + 2.5 0.5a + a2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 0.5a + a2 = 2.5 The a term is a. 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. 0.5a + 0.25 + a2 = 2.5 + 0.25 Reorder the terms: 0.25 + 0.5a + a2 = 2.5 + 0.25 Combine like terms: 2.5 + 0.25 = 2.75 0.25 + 0.5a + a2 = 2.75 Factor a perfect square on the left side: (a + 0.5)(a + 0.5) = 2.75 Calculate the square root of the right side: 1.658312395 Break this problem into two subproblems by setting (a + 0.5) equal to 1.658312395 and -1.658312395.Subproblem 1
a + 0.5 = 1.658312395 Simplifying a + 0.5 = 1.658312395 Reorder the terms: 0.5 + a = 1.658312395 Solving 0.5 + a = 1.658312395 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 = 1.658312395 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + a = 1.658312395 + -0.5 a = 1.658312395 + -0.5 Combine like terms: 1.658312395 + -0.5 = 1.158312395 a = 1.158312395 Simplifying a = 1.158312395Subproblem 2
a + 0.5 = -1.658312395 Simplifying a + 0.5 = -1.658312395 Reorder the terms: 0.5 + a = -1.658312395 Solving 0.5 + a = -1.658312395 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 = -1.658312395 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + a = -1.658312395 + -0.5 a = -1.658312395 + -0.5 Combine like terms: -1.658312395 + -0.5 = -2.158312395 a = -2.158312395 Simplifying a = -2.158312395Solution
