Simplifying 0.2a2 + 12a + 0.9 = 0 Reorder the terms: 0.9 + 12a + 0.2a2 = 0 Solving 0.9 + 12a + 0.2a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. 4.5 + 60a + a2 = 0 Move the constant term to the right: Add '-4.5' to each side of the equation. 4.5 + 60a + -4.5 + a2 = 0 + -4.5 Reorder the terms: 4.5 + -4.5 + 60a + a2 = 0 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + 60a + a2 = 0 + -4.5 60a + a2 = 0 + -4.5 Combine like terms: 0 + -4.5 = -4.5 60a + a2 = -4.5 The a term is 60a. Take half its coefficient (30). Square it (900) and add it to both sides. Add '900' to each side of the equation. 60a + 900 + a2 = -4.5 + 900 Reorder the terms: 900 + 60a + a2 = -4.5 + 900 Combine like terms: -4.5 + 900 = 895.5 900 + 60a + a2 = 895.5 Factor a perfect square on the left side: (a + 30)(a + 30) = 895.5 Calculate the square root of the right side: 29.924906015 Break this problem into two subproblems by setting (a + 30) equal to 29.924906015 and -29.924906015.Subproblem 1
a + 30 = 29.924906015 Simplifying a + 30 = 29.924906015 Reorder the terms: 30 + a = 29.924906015 Solving 30 + a = 29.924906015 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-30' to each side of the equation. 30 + -30 + a = 29.924906015 + -30 Combine like terms: 30 + -30 = 0 0 + a = 29.924906015 + -30 a = 29.924906015 + -30 Combine like terms: 29.924906015 + -30 = -0.075093985 a = -0.075093985 Simplifying a = -0.075093985Subproblem 2
a + 30 = -29.924906015 Simplifying a + 30 = -29.924906015 Reorder the terms: 30 + a = -29.924906015 Solving 30 + a = -29.924906015 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-30' to each side of the equation. 30 + -30 + a = -29.924906015 + -30 Combine like terms: 30 + -30 = 0 0 + a = -29.924906015 + -30 a = -29.924906015 + -30 Combine like terms: -29.924906015 + -30 = -59.924906015 a = -59.924906015 Simplifying a = -59.924906015Solution
The solution to the problem is based on the solutions from the subproblems. a = {-0.075093985, -59.924906015}
