Simplifying 2a + 5a(a + -1) = 6 Reorder the terms: 2a + 5a(-1 + a) = 6 2a + (-1 * 5a + a * 5a) = 6 2a + (-5a + 5a2) = 6 Combine like terms: 2a + -5a = -3a -3a + 5a2 = 6 Solving -3a + 5a2 = 6 Solving for variable 'a'. Reorder the terms: -6 + -3a + 5a2 = 6 + -6 Combine like terms: 6 + -6 = 0 -6 + -3a + 5a2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.2 + -0.6a + a2 = 0 Move the constant term to the right: Add '1.2' to each side of the equation. -1.2 + -0.6a + 1.2 + a2 = 0 + 1.2 Reorder the terms: -1.2 + 1.2 + -0.6a + a2 = 0 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + -0.6a + a2 = 0 + 1.2 -0.6a + a2 = 0 + 1.2 Combine like terms: 0 + 1.2 = 1.2 -0.6a + a2 = 1.2 The a term is -0.6a. Take half its coefficient (-0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. -0.6a + 0.09 + a2 = 1.2 + 0.09 Reorder the terms: 0.09 + -0.6a + a2 = 1.2 + 0.09 Combine like terms: 1.2 + 0.09 = 1.29 0.09 + -0.6a + a2 = 1.29 Factor a perfect square on the left side: (a + -0.3)(a + -0.3) = 1.29 Calculate the square root of the right side: 1.135781669 Break this problem into two subproblems by setting (a + -0.3) equal to 1.135781669 and -1.135781669.Subproblem 1
a + -0.3 = 1.135781669 Simplifying a + -0.3 = 1.135781669 Reorder the terms: -0.3 + a = 1.135781669 Solving -0.3 + a = 1.135781669 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + a = 1.135781669 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + a = 1.135781669 + 0.3 a = 1.135781669 + 0.3 Combine like terms: 1.135781669 + 0.3 = 1.435781669 a = 1.435781669 Simplifying a = 1.435781669Subproblem 2
a + -0.3 = -1.135781669 Simplifying a + -0.3 = -1.135781669 Reorder the terms: -0.3 + a = -1.135781669 Solving -0.3 + a = -1.135781669 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + a = -1.135781669 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + a = -1.135781669 + 0.3 a = -1.135781669 + 0.3 Combine like terms: -1.135781669 + 0.3 = -0.835781669 a = -0.835781669 Simplifying a = -0.835781669Solution
The solution to the problem is based on the solutions from the subproblems. a = {1.435781669, -0.835781669}
