Simplifying 186 = 2x2 + -8x + 13 Reorder the terms: 186 = 13 + -8x + 2x2 Solving 186 = 13 + -8x + 2x2 Solving for variable 'x'. Combine like terms: 186 + -13 = 173 173 + 8x + -2x2 = 13 + -8x + 2x2 + -13 + 8x + -2x2 Reorder the terms: 173 + 8x + -2x2 = 13 + -13 + -8x + 8x + 2x2 + -2x2 Combine like terms: 13 + -13 = 0 173 + 8x + -2x2 = 0 + -8x + 8x + 2x2 + -2x2 173 + 8x + -2x2 = -8x + 8x + 2x2 + -2x2 Combine like terms: -8x + 8x = 0 173 + 8x + -2x2 = 0 + 2x2 + -2x2 173 + 8x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 173 + 8x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -86.5 + -4x + x2 = 0 Move the constant term to the right: Add '86.5' to each side of the equation. -86.5 + -4x + 86.5 + x2 = 0 + 86.5 Reorder the terms: -86.5 + 86.5 + -4x + x2 = 0 + 86.5 Combine like terms: -86.5 + 86.5 = 0.0 0.0 + -4x + x2 = 0 + 86.5 -4x + x2 = 0 + 86.5 Combine like terms: 0 + 86.5 = 86.5 -4x + x2 = 86.5 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 86.5 + 4 Reorder the terms: 4 + -4x + x2 = 86.5 + 4 Combine like terms: 86.5 + 4 = 90.5 4 + -4x + x2 = 90.5 Factor a perfect square on the left side: (x + -2)(x + -2) = 90.5 Calculate the square root of the right side: 9.513148795 Break this problem into two subproblems by setting (x + -2) equal to 9.513148795 and -9.513148795.Subproblem 1
x + -2 = 9.513148795 Simplifying x + -2 = 9.513148795 Reorder the terms: -2 + x = 9.513148795 Solving -2 + x = 9.513148795 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 9.513148795 + 2 Combine like terms: -2 + 2 = 0 0 + x = 9.513148795 + 2 x = 9.513148795 + 2 Combine like terms: 9.513148795 + 2 = 11.513148795 x = 11.513148795 Simplifying x = 11.513148795Subproblem 2
x + -2 = -9.513148795 Simplifying x + -2 = -9.513148795 Reorder the terms: -2 + x = -9.513148795 Solving -2 + x = -9.513148795 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -9.513148795 + 2 Combine like terms: -2 + 2 = 0 0 + x = -9.513148795 + 2 x = -9.513148795 + 2 Combine like terms: -9.513148795 + 2 = -7.513148795 x = -7.513148795 Simplifying x = -7.513148795Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.513148795, -7.513148795}
