Simplifying a2 + 0.7a + -0.1 = 0 Reorder the terms: -0.1 + 0.7a + a2 = 0 Solving -0.1 + 0.7a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + 0.7a + 0.1 + a2 = 0 + 0.1 Reorder the terms: -0.1 + 0.1 + 0.7a + a2 = 0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + 0.7a + a2 = 0 + 0.1 0.7a + a2 = 0 + 0.1 Combine like terms: 0 + 0.1 = 0.1 0.7a + a2 = 0.1 The a term is 0.7a. Take half its coefficient (0.35). Square it (0.1225) and add it to both sides. Add '0.1225' to each side of the equation. 0.7a + 0.1225 + a2 = 0.1 + 0.1225 Reorder the terms: 0.1225 + 0.7a + a2 = 0.1 + 0.1225 Combine like terms: 0.1 + 0.1225 = 0.2225 0.1225 + 0.7a + a2 = 0.2225 Factor a perfect square on the left side: (a + 0.35)(a + 0.35) = 0.2225 Calculate the square root of the right side: 0.471699057 Break this problem into two subproblems by setting (a + 0.35) equal to 0.471699057 and -0.471699057.Subproblem 1
a + 0.35 = 0.471699057 Simplifying a + 0.35 = 0.471699057 Reorder the terms: 0.35 + a = 0.471699057 Solving 0.35 + a = 0.471699057 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.35' to each side of the equation. 0.35 + -0.35 + a = 0.471699057 + -0.35 Combine like terms: 0.35 + -0.35 = 0.00 0.00 + a = 0.471699057 + -0.35 a = 0.471699057 + -0.35 Combine like terms: 0.471699057 + -0.35 = 0.121699057 a = 0.121699057 Simplifying a = 0.121699057Subproblem 2
a + 0.35 = -0.471699057 Simplifying a + 0.35 = -0.471699057 Reorder the terms: 0.35 + a = -0.471699057 Solving 0.35 + a = -0.471699057 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.35' to each side of the equation. 0.35 + -0.35 + a = -0.471699057 + -0.35 Combine like terms: 0.35 + -0.35 = 0.00 0.00 + a = -0.471699057 + -0.35 a = -0.471699057 + -0.35 Combine like terms: -0.471699057 + -0.35 = -0.821699057 a = -0.821699057 Simplifying a = -0.821699057Solution
