Simplifying (3a + -7) + (2a2 + -8a + 6) = 0 Reorder the terms: (-7 + 3a) + (2a2 + -8a + 6) = 0 Remove parenthesis around (-7 + 3a) -7 + 3a + (2a2 + -8a + 6) = 0 Reorder the terms: -7 + 3a + (6 + -8a + 2a2) = 0 Remove parenthesis around (6 + -8a + 2a2) -7 + 3a + 6 + -8a + 2a2 = 0 Reorder the terms: -7 + 6 + 3a + -8a + 2a2 = 0 Combine like terms: -7 + 6 = -1 -1 + 3a + -8a + 2a2 = 0 Combine like terms: 3a + -8a = -5a -1 + -5a + 2a2 = 0 Solving -1 + -5a + 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'. -0.5 + -2.5a + a2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -2.5a + 0.5 + a2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -2.5a + a2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -2.5a + a2 = 0 + 0.5 -2.5a + a2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -2.5a + a2 = 0.5 The a term is -2.5a. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5a + 1.5625 + a2 = 0.5 + 1.5625 Reorder the terms: 1.5625 + -2.5a + a2 = 0.5 + 1.5625 Combine like terms: 0.5 + 1.5625 = 2.0625 1.5625 + -2.5a + a2 = 2.0625 Factor a perfect square on the left side: (a + -1.25)(a + -1.25) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (a + -1.25) equal to 1.436140662 and -1.436140662.Subproblem 1
a + -1.25 = 1.436140662 Simplifying a + -1.25 = 1.436140662 Reorder the terms: -1.25 + a = 1.436140662 Solving -1.25 + a = 1.436140662 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + a = 1.436140662 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + a = 1.436140662 + 1.25 a = 1.436140662 + 1.25 Combine like terms: 1.436140662 + 1.25 = 2.686140662 a = 2.686140662 Simplifying a = 2.686140662Subproblem 2
a + -1.25 = -1.436140662 Simplifying a + -1.25 = -1.436140662 Reorder the terms: -1.25 + a = -1.436140662 Solving -1.25 + a = -1.436140662 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + a = -1.436140662 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + a = -1.436140662 + 1.25 a = -1.436140662 + 1.25 Combine like terms: -1.436140662 + 1.25 = -0.186140662 a = -0.186140662 Simplifying a = -0.186140662Solution
