Simplifying (3a2 + 2a + -2) + -1(a2 + -3a + 7) = 0 Reorder the terms: (-2 + 2a + 3a2) + -1(a2 + -3a + 7) = 0 Remove parenthesis around (-2 + 2a + 3a2) -2 + 2a + 3a2 + -1(a2 + -3a + 7) = 0 Reorder the terms: -2 + 2a + 3a2 + -1(7 + -3a + a2) = 0 -2 + 2a + 3a2 + (7 * -1 + -3a * -1 + a2 * -1) = 0 -2 + 2a + 3a2 + (-7 + 3a + -1a2) = 0 Reorder the terms: -2 + -7 + 2a + 3a + 3a2 + -1a2 = 0 Combine like terms: -2 + -7 = -9 -9 + 2a + 3a + 3a2 + -1a2 = 0 Combine like terms: 2a + 3a = 5a -9 + 5a + 3a2 + -1a2 = 0 Combine like terms: 3a2 + -1a2 = 2a2 -9 + 5a + 2a2 = 0 Solving -9 + 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'. -4.5 + 2.5a + a2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + 2.5a + 4.5 + a2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + 2.5a + a2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + 2.5a + a2 = 0 + 4.5 2.5a + a2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 2.5a + a2 = 4.5 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 = 4.5 + 1.5625 Reorder the terms: 1.5625 + 2.5a + a2 = 4.5 + 1.5625 Combine like terms: 4.5 + 1.5625 = 6.0625 1.5625 + 2.5a + a2 = 6.0625 Factor a perfect square on the left side: (a + 1.25)(a + 1.25) = 6.0625 Calculate the square root of the right side: 2.46221445 Break this problem into two subproblems by setting (a + 1.25) equal to 2.46221445 and -2.46221445.Subproblem 1
a + 1.25 = 2.46221445 Simplifying a + 1.25 = 2.46221445 Reorder the terms: 1.25 + a = 2.46221445 Solving 1.25 + a = 2.46221445 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 = 2.46221445 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + a = 2.46221445 + -1.25 a = 2.46221445 + -1.25 Combine like terms: 2.46221445 + -1.25 = 1.21221445 a = 1.21221445 Simplifying a = 1.21221445Subproblem 2
a + 1.25 = -2.46221445 Simplifying a + 1.25 = -2.46221445 Reorder the terms: 1.25 + a = -2.46221445 Solving 1.25 + a = -2.46221445 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 = -2.46221445 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + a = -2.46221445 + -1.25 a = -2.46221445 + -1.25 Combine like terms: -2.46221445 + -1.25 = -3.71221445 a = -3.71221445 Simplifying a = -3.71221445Solution
The solution to the problem is based on the solutions from the subproblems. a = {1.21221445, -3.71221445}
