Simplifying 5x2 + -8x + -67 = -2 Reorder the terms: -67 + -8x + 5x2 = -2 Solving -67 + -8x + 5x2 = -2 Solving for variable 'x'. Reorder the terms: -67 + 2 + -8x + 5x2 = -2 + 2 Combine like terms: -67 + 2 = -65 -65 + -8x + 5x2 = -2 + 2 Combine like terms: -2 + 2 = 0 -65 + -8x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -13 + -1.6x + x2 = 0 Move the constant term to the right: Add '13' to each side of the equation. -13 + -1.6x + 13 + x2 = 0 + 13 Reorder the terms: -13 + 13 + -1.6x + x2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -1.6x + x2 = 0 + 13 -1.6x + x2 = 0 + 13 Combine like terms: 0 + 13 = 13 -1.6x + x2 = 13 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = 13 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = 13 + 0.64 Combine like terms: 13 + 0.64 = 13.64 0.64 + -1.6x + x2 = 13.64 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 13.64 Calculate the square root of the right side: 3.693237063 Break this problem into two subproblems by setting (x + -0.8) equal to 3.693237063 and -3.693237063.Subproblem 1
x + -0.8 = 3.693237063 Simplifying x + -0.8 = 3.693237063 Reorder the terms: -0.8 + x = 3.693237063 Solving -0.8 + x = 3.693237063 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 3.693237063 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 3.693237063 + 0.8 x = 3.693237063 + 0.8 Combine like terms: 3.693237063 + 0.8 = 4.493237063 x = 4.493237063 Simplifying x = 4.493237063Subproblem 2
x + -0.8 = -3.693237063 Simplifying x + -0.8 = -3.693237063 Reorder the terms: -0.8 + x = -3.693237063 Solving -0.8 + x = -3.693237063 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -3.693237063 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -3.693237063 + 0.8 x = -3.693237063 + 0.8 Combine like terms: -3.693237063 + 0.8 = -2.893237063 x = -2.893237063 Simplifying x = -2.893237063Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.493237063, -2.893237063}
