Simplifying 2a2 + 7a + -10 = 0 Reorder the terms: -10 + 7a + 2a2 = 0 Solving -10 + 7a + 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'. -5 + 3.5a + a2 = 0 Move the constant term to the right: Add '5' to each side of the equation. -5 + 3.5a + 5 + a2 = 0 + 5 Reorder the terms: -5 + 5 + 3.5a + a2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 3.5a + a2 = 0 + 5 3.5a + a2 = 0 + 5 Combine like terms: 0 + 5 = 5 3.5a + a2 = 5 The a term is 3.5a. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5a + 3.0625 + a2 = 5 + 3.0625 Reorder the terms: 3.0625 + 3.5a + a2 = 5 + 3.0625 Combine like terms: 5 + 3.0625 = 8.0625 3.0625 + 3.5a + a2 = 8.0625 Factor a perfect square on the left side: (a + 1.75)(a + 1.75) = 8.0625 Calculate the square root of the right side: 2.839454173 Break this problem into two subproblems by setting (a + 1.75) equal to 2.839454173 and -2.839454173.Subproblem 1
a + 1.75 = 2.839454173 Simplifying a + 1.75 = 2.839454173 Reorder the terms: 1.75 + a = 2.839454173 Solving 1.75 + a = 2.839454173 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + a = 2.839454173 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + a = 2.839454173 + -1.75 a = 2.839454173 + -1.75 Combine like terms: 2.839454173 + -1.75 = 1.089454173 a = 1.089454173 Simplifying a = 1.089454173Subproblem 2
a + 1.75 = -2.839454173 Simplifying a + 1.75 = -2.839454173 Reorder the terms: 1.75 + a = -2.839454173 Solving 1.75 + a = -2.839454173 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + a = -2.839454173 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + a = -2.839454173 + -1.75 a = -2.839454173 + -1.75 Combine like terms: -2.839454173 + -1.75 = -4.589454173 a = -4.589454173 Simplifying a = -4.589454173Solution
