Simplifying 0.9 = 2a + -1a2 Solving 0.9 = 2a + -1a2 Solving for variable 'a'. Reorder the terms: 0.9 + -2a + a2 = 2a + -2a + -1a2 + a2 Combine like terms: 2a + -2a = 0 0.9 + -2a + a2 = 0 + -1a2 + a2 0.9 + -2a + a2 = -1a2 + a2 Combine like terms: -1a2 + a2 = 0 0.9 + -2a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '-0.9' to each side of the equation. 0.9 + -2a + -0.9 + a2 = 0 + -0.9 Reorder the terms: 0.9 + -0.9 + -2a + a2 = 0 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + -2a + a2 = 0 + -0.9 -2a + a2 = 0 + -0.9 Combine like terms: 0 + -0.9 = -0.9 -2a + a2 = -0.9 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 = -0.9 + 1 Reorder the terms: 1 + -2a + a2 = -0.9 + 1 Combine like terms: -0.9 + 1 = 0.1 1 + -2a + a2 = 0.1 Factor a perfect square on the left side: (a + -1)(a + -1) = 0.1 Calculate the square root of the right side: 0.316227766 Break this problem into two subproblems by setting (a + -1) equal to 0.316227766 and -0.316227766.Subproblem 1
a + -1 = 0.316227766 Simplifying a + -1 = 0.316227766 Reorder the terms: -1 + a = 0.316227766 Solving -1 + a = 0.316227766 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 = 0.316227766 + 1 Combine like terms: -1 + 1 = 0 0 + a = 0.316227766 + 1 a = 0.316227766 + 1 Combine like terms: 0.316227766 + 1 = 1.316227766 a = 1.316227766 Simplifying a = 1.316227766Subproblem 2
a + -1 = -0.316227766 Simplifying a + -1 = -0.316227766 Reorder the terms: -1 + a = -0.316227766 Solving -1 + a = -0.316227766 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 = -0.316227766 + 1 Combine like terms: -1 + 1 = 0 0 + a = -0.316227766 + 1 a = -0.316227766 + 1 Combine like terms: -0.316227766 + 1 = 0.683772234 a = 0.683772234 Simplifying a = 0.683772234Solution
The solution to the problem is based on the solutions from the subproblems. a = {1.316227766, 0.683772234}
