Simplifying 4a2 + -8a + -11 = 0 Reorder the terms: -11 + -8a + 4a2 = 0 Solving -11 + -8a + 4a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.75 + -2a + a2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + -2a + 2.75 + a2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + -2a + a2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + -2a + a2 = 0 + 2.75 -2a + a2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 -2a + a2 = 2.75 The a term is -2a. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2a + 1 + a2 = 2.75 + 1 Reorder the terms: 1 + -2a + a2 = 2.75 + 1 Combine like terms: 2.75 + 1 = 3.75 1 + -2a + a2 = 3.75 Factor a perfect square on the left side: (a + -1)(a + -1) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (a + -1) equal to 1.936491673 and -1.936491673.Subproblem 1
a + -1 = 1.936491673 Simplifying a + -1 = 1.936491673 Reorder the terms: -1 + a = 1.936491673 Solving -1 + a = 1.936491673 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + a = 1.936491673 + 1 Combine like terms: -1 + 1 = 0 0 + a = 1.936491673 + 1 a = 1.936491673 + 1 Combine like terms: 1.936491673 + 1 = 2.936491673 a = 2.936491673 Simplifying a = 2.936491673Subproblem 2
a + -1 = -1.936491673 Simplifying a + -1 = -1.936491673 Reorder the terms: -1 + a = -1.936491673 Solving -1 + a = -1.936491673 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + a = -1.936491673 + 1 Combine like terms: -1 + 1 = 0 0 + a = -1.936491673 + 1 a = -1.936491673 + 1 Combine like terms: -1.936491673 + 1 = -0.936491673 a = -0.936491673 Simplifying a = -0.936491673Solution
The solution to the problem is based on the solutions from the subproblems. a = {2.936491673, -0.936491673}
